Prospect Park Boathouse, ca. 1909.

The Prospect Park Boathouse is a two-story Beaux-Arts style structure clad in terra cotta. The pavilion, which sits on the north shore of the park's lake, was constructed in 1905 to the plans of the firm of Helmle & Huberty. The architects modeled the building on the library of St. Mark’s Cathedral in Venice.

Almost demolished in 1964 when it was an deteriorating and underused structure, the Boathouse became one of the first buildings to be landmarked in 1965, the year the Landmarks Law was passed. The building was restored during various efforts in the 1970s and 1980s. Today, the building houses the Audubon Center, the Audubon Society's only urban interpretive center in the United States, and is a popular wedding venue.
