According to a 1969 interview with former estate grounds superintendent Sylvester Cangero, the cottage (now Kumble Hall) was the first place that he was assigned when he began his employment for William Prime in February 1911. Mr. Cangero remembered it being very cold while he helped carry bricks to the top of the building during the construction of the chimney. According to Mr. Cangero, the Prime family called the building the game house.

During its years as a game house, roosters were kept on one side of the building and hens on the other. “The middle room (on the first floor) was the scene of cock fights complete with a fight ring and illustrious spectators,” Mr. Cangero said. Since cock fighting was illegal, the Primes had a staircase installed leading to the top floor that was hidden behind a large painting. A lookout stationed in the building’s cupola would alert guests if the police were spotted in the vicinity. After guests rushed upstairs, the staircase would be raised into the ceiling and disappear.

Although the staircase has been rendered immobile for many years, the huge hinges that lifted the staircase were removed during renovation in 2005 to the third floor of the building. The only remaining evidence of the staircase ever moving are the small hinges, which are still visible under the banister.

When the Huttons purchased the estate from Mr. and Mrs. Prime in 1921 they did not approve of the “games” that had taken place in the game house and converted the building into guest accommodations. The building was renamed Post Cottage.

Post Cottage's greatest claim to fame was during the months of July through October 1940, when the Grand Ducal family of Luxembourg lived in the building after they fled to America due to the Nazi invasion of their country.

In September 2004 Luxembourg’s reigning monarch Grand Duke Henri came to the C.W. Post Campus to see first hand the former estate and the guesthouse where his relatives lived while in exile.
