Still House, a Matinecock mansion designed in the 1920s by Gold Coast architect Bradley Delehanty, is on the market for $12.5 million.

Delehanty designed the Georgian Colonial for Paul Cravath, a prominent Manhattan lawyer and a presiding partner of the law firm today known as Cravath, Swaine & Moore. Still House was Cravath's fourth home in the area, and he chose to have it made of brick because fires destroyed his first two, according to the blog Old Long Island.

The home, which has eight bedrooms and 10 fireplaces, sits on 37 landscaped acres with an in-ground pool and a pool house.

Among the home's luxurious features is a two-story library said to be made with wood paneling salvaged from the RMS Mauretania, the sister ship of the ill-fated Lusitania, says listing agent Joann Natale Fischer of Coach Realtors.

The house also has a movie theater that seats 15.
