3. Helen Gould built a bowling pavilion and recreation center at Lyndhurst
In addition to educating the children of Tarrytown, Helen Gould aimed to improve Lyndhurst Mansion in the architectural sense. In 1894, she built a bowling pavilion and recreation center on property to add to the already luxurious lifestyle of those who lived there. However, the recreation center was created for the community as well, acting occasionally as the site for her sewing classes.
Said to be one of the first regulation bowling alleys in the nation, the two alley bowling lane survives to this day. When the National Trust for Historic Preservation gained possession of the mansion in 1961, they found that the bowling alley had fallen into disrepair after decades of neglect. Over the next six decades, many would work to refurbish the bowling alley, often pausing when money ran out. Officially completed since 2017, tourists can visit the bowling alley and book the lanes for private events.
