“Clinton Avenue, Brooklyn’s Show Street,” from a Brooklyn Eagle postcard series 1905-07.

From right to left are: no. 245, the George Dupont Pratt mansion, now Burns hall of St. Joseph’s College; no. 241, the Charles Millard Pratt house, now the residence of the Roman Catholic Bishop of Brooklyn; and no. 229, the Frederic B. Pratt House.

The latter, today known as the Catherine Ladd Pratt House, is a gray brick Georgian/Renaissance Revival mansion designed by Babb, Cook & Willard. Built in 1895, the house is notable for its inventive solution to the adjacent rowhouses at the property’s northern edge: a two-story portico entranceway with a second-level colonnade with pillars carved to look like female figures.
