This June, the Roslyn Landmark Society is hosting three extraordinary house tours over three separate weekends.

Three of Long Island’s most exclusive houses have granted access to a limited number of Roslyn Landmark Society members for private tours. Each event is a dream come true for Long Island history buffs, art enthusiasts, and architecture aficionados alike.

Private tours will take place at the John Mackay III House (Happy House), the Gertrude Vanderbilt Whitney Studio, and the Thomas Clapham House (Wenlo).

Roslyn Landmark Society members will have the opportunity to attend one or all events scheduled. Space is limited so tickets will be assigned on a first-come, first-served basis.

Each event includes live musicians with a wine and cheese reception followed by a private tour of one of these three legendary Long Island houses. Please register at roslynlandmarks.org by clicking the “Events” tab and choosing the proper event.
