It sits on a hill just outside of New York City, completely empty and, for years, decaying and nearly forgotten…

Alder Manor 01

This is Alder Manor, and it’s without question one of the most amazing places I’ve ever had the pleasure of scouting. Built in 1912 by William Boyce Thompson, an extremely successful copper magnate, his plan was for a 72-room country estate for entertaining (he lived in New York City at the time) on 22 acres of hilltop land in then rural Yonkers.

After both he and his wife died, the mansion was traded between owners who had no use for it and eventually wound up abandoned. Thankfully, it’s been purchased in recent years, and its restoration is slowly taking shape.

When you first enter, you find yourself in the enormous Main Hall, with the huge grand staircase off to one side. This is about when you start to wonder how such a place could ever be abandoned.

Reverse of the main hall. We’re going to start by heading down that hallway…

Which leads to the incredible library:

Standing in the reverse corner, with a great stone fireplace and working chandeliers. I especially love how the books go over the doorway.

Alder Manor 05

From a distance, the room looks like it’s in excellent condition. It’s only when you get a little closer that you realize how much restoration is needed. Wood is rotting, the paint is fading and chipped…This gives you a better idea (still, a great candidate for restoration):

Next door to the library is the Ballroom, with rich reds and blues complementing the mahogany woodwork:

A painting over the fireplace is still in excellent shape:

Across the hall is the dining room, as a short hallway behind where I was standing leads to the Kitchen:

Heading now upstairs…

Brings you to the second floor landing, featuring an organ…

…which connects to pipes way up on the third floor.

My favorite room in Alder Manor is just down the hall from the pipe organ: an indoor pool. On the second floor. Built in 1912.

It’d be so great to see this restored to working order. The faded lime green paint, the black and white tiling on the pool…Apparently, there used to be antique Tiffany glass here, until someone found out and stole it.

As you’re walking through the mansion, there are tons of artistic details to be found everywhere, like this bit of a ceiling painting:

This was the design on the wall abutting the stairs:

There are also a few missing details…

Besides the pool, the second and third floors are essentially endless amounts of bedrooms…

Some have been fixed up.

At the end of the second floor is a conservatory and small balcony:

The gardens behind the manor are absolutely beautiful despite their decay:

A reader writes:

“I worked at the Boyce Thompson Institute for Plant Research from 1955-1978 when the Institute moved to the Cornell University campus. It’s still there and is housed in a beautiful building constructed by Cornell. I visited Alder Manor several times over the years, including two weddings. Its beauty is self evident from the photos. Col. Thompson (an honorary title) loved his gardens so much that he decided to build and endow a plant research institution to learn how plants “work”. It was finished in 1923 and dedicated in 1924.

“Shortly after the Sisters of Mercy took over the estate, a piece of pottery was discovered in a cabinet. It turned out to be extremely valuable. As I understand it, it was Etruscan and was sold for “more money than was paid for the estate”. At least that’s the story I was told.

“W.B. Thompson was quite a man. The Colonel title was bestowed upon him when he led a mission to Russia after WW I. He actually gave some money to feed Russians in poverty and became known as the ‘Red of Wall Street.’”

If you’re interested in using Alder Manor for an event, film shoot, or pretty much anything, send me an email to nycscout@gmail.com.

PS – For anyone counting, there was a front hall, library, ballroom, dining room, kitchen, and conservatory. In addition, there were empty rooms on the ground floor that could have easily served as the billiard room, lounge, and study.

PPS – Across the street from the manor in FAR worse shape is the abandoned Boyce Research Institute. I took some pictures which I’ll post in a future entry.

    We filmed a tv show in this mansion. Pictures alone can’t describe just how breath taking every room is. I hope to someday visit again.

    I attended college there from 1989-1991. I stumbled upon this blog and am saddened to hear that it has been abandoned for many years:(
    It was a beautiful campus when I went there and I am grateful that I had the opportunity to spend so much time there. I cannot believe that it is in such disrepair today. I hope the new owners can restore it to its original beauty. Shame on Yonkers!

    It makes me so happy to see that the manor house is being restored. I went to school at Elizabeth Seton and remember the manor well. When I went to school the new building had been built and the manor was used mainly as a dorm for boarding students. Many of the boarding students came from South and Central America. It was a wonderful time.

    It was sad, however, when the high school closed its doors with the last graduating class of 1964. Elizabeth Seton Junior College opened its doors in 1962 and for awhile we in the high school attended school in the same building as the College students.

    The Manor was always such a beautiful building and well kept when schools were open. In 1964 or 65 the new College dorm building was opened. I never imagined that the College would have closed its doors and the campus fall into disrepair. I do hope Tara has a lot of success.

      Hi Pat
      Don’t know if you would remember me ( Julie Duffy Miller). I attended the HS from ’60 to 61. About 12 of us came from St. Lawrence academy in NYC after it also closed. Many of us went on to the college.
      Toni Cavanaugh Dee, Merrily Alberti Silverson and I are trying to find old classmates since 2011 will be our 50th Anniversary.
      Are you, by any chance in contact with any classmates from there? Perhaps you know some from the class of 61?
      I would really appreciate any information you might be able to provide.
      As far reaching as the internet is, it is still hard to find people without contacts and luck.
      Thanks

      Morella and Susana:
      Las recuerdo perfectamente. Se hospedaban en el Wellington Hotel y yo me quedaba de vez en cuando alli con los Osio. Me dio mucha tristeza ver como se ha acabado Seton. Today, Thanksgiving Day, I give thanks for the opportunity to have experienced my first encounter with the American culture and Thanksgiving tradition in such an unbelievable place. I also took my family there and they were just in awe.

      Hello Morella It is your classmate Pat Doyle. Hard to believe that we are grandparents. It seems like yesterday we were in our high school uniforms and studying for Regents.
      I do hope that almost 50 years has been kind to you.
      Oh, I did buy that motorcycle I talked about. Just bought another for my 60th birthday in 2007, an 1100 cc Honda Sabre cruiser/touring bike.
      I spent my life in the horse racing industry. I had a marvelous life.

      Oh, I found Miss Car and she married Mr. Casper and they are happy. They live in Cape Cod but travel extensively.

      How about a 50th reunion in 2014 at the Manor?

    I was a member of the first class at Elizabeth Seton College from 1961-1963 and remember fondly all the crazy (we thought) things we did when the Sisters went to bed. We were always going down to the kitchens to see what was in the fridge. At that time there were many girls from South America, Central America and the Dominican Republic in both the high school and college and we had a wonderful time on the weekends. It was like one big, happy family. Swimming in the pool certainly a plus.
    I was saddened to hear that it had gone into disrepair. The last I heard it was owned by Iona and I thought it still was. It is good that someone is trying to restore it to its original beauty. Even in the 60’s it was a wonderful place to be.

      Hi Maureen.
      Are you in contact with any others from our class. Almost time for a 50th reunion!
      Let me know if you are interested in working on this.

    I attended Elizabeth Seton College 1962 to 1964. I remember living in the bedroom over the beautiful front door! We loved the library and the gorgeous rooms for visitors or just quiet study time. We moved to the new dorm hall for our second year. The grounds were just lovely to explore and walk around. I remember the pool and playing tennis and badminton in the gym. The Sisters of Charity were just so kind and supportive to all of us. Glad to see it’s being restored!

    Thank you for sharing picture of this amazingly grand and beautiful house. How could anyone abandon it and make the decision not to live in it? So glad that it is being restored.

    I don’t know if anyone already pointed this out, but as soon as I saw the FIRST picture I RECOGNIZED the house from the MGMT ‘Flash Delirium’ music video. I am positive that this is the house because I have watched the music video a lot+my love for spectacular houses, it is hard to forget that house! So strange that I would stumbleupon this website I got goosebumps right away just from recognizing the house. Actually I don’t know if that is sad or not…

    Thank you so much for this journey. I attended Elizabeth Seton College from 1971-1973. The grounds were always spectacular and the mansion, well, words could not describe it. I was shocked when my husband and I drove in a few years ago. It had just been taken over by Tara Circle. We spoke to a lovely man who took the time to explain what had happened over the years. I was so saddened by what I heard. I am elated to see how they have rescued this jewel of New York. Thank you Tara Circle and a heartfelt thanks to blog for presenting Alder Manor w/ such appreciation.

    I attended Elizabeth Seton High School staffed by the Sisters of Charity (not Mercy). I graduated in 1957 and was in the last freshman class to be in the house. The following year we moved into a newly constructed building near the tennis courts. Our class met in what had been a bedroom on the second floor. We had 11 in our class and 13 in the other class in another room. I just dreamt about the house and was prompted by that to investigate its current status. What a treasure!

    Do they rent out the mansion for weddings? It would be a gorgeous setting for a wedding ceremony and reception.

    I attended Elizabeth Seton College from 1979-(Class of 81′) I have fond memories of this spectacular mansion which are more appreciative now than when I attended—Hey, it was College. I frequently studied in the basement library which had a wonderful collage of colors and art blending with beautiful wooden architecture. Also had some great times and memories of our Spring Cotillion, class room education–in this beautiful mansion setting no less–as well as volunteering with various fund-raising or political events that were held there regularly. Thank you so much for these wonderful photos that help me reflect on a time in my life that makes it feel more special to have experienced a part of this historical landmark.
