The Matthew Clarkson Mansion, later home to the Midwood Club and the Union League Club, Flatbush; ca. 1880. Built in 1836 for Matthew Clarkson, a member of the prominent Flatbush family, this temple-fronted classical mansion once sat on a large tree-lined plot west of Flatbush Avenue. Following Clarkson's death in 1883, at the age of 87, the mansion became the first home of the Midwood Club, a gentlemen's social organization founded in 1889. The Club would eventually buy out Clarkson's heirs and assume ownership of the building. By 1917, the Midwood Club's membership had declined considerably and the club itself was on the brink of extinction. That year, the Union League Club, formerly located at Grant Square, took over the former Clarkson mansion and restored its place in Brooklyn social life. In 1937, the building became the Y.M.C.A.'s Flatbush chapter. After a January 1940 fire caused significant damage, the once-proud 104 year old estate was sold for development and razed.

Prospect Park Parade Grounds, ca. 1895. Parade Grounds at the southernmost tip of Prospect Park, named for its use as a drill field for Union Soldiers during the Civil War, once had 13 baseball fields. The Parade Grounds sent more players to Major League Baseball than any other New York ballpark. According to Bob McGee, author of “The Greatest Ballpark Ever: Ebbets Field and the Story of the Brooklyn Dodgers,” the Parade Grounds was not just a neighborhood park. "It was a boroughwide showcase for young teenage talent in the city’s most populous borough, which, coincidentally, had far and away traditionally the greatest number of amateur teams.” Among the future major leaguers who played there were: Koufax; Hoyt; Joe and Frank Torre; Bob and Ken Aspromonte; Cy Block; Chuck Connors, aka “The Rifleman”; Harry Eisenstat; Sid Gordon; Buddy Hassett; Billy Jurges; Bill Lohrman; Sam Mele; Saul Rogovin; and Marius Russo.

Peristyle, unknown date. Located near the Parade Grounds at the southern border of Prospect Park, the McKim, Mead & White-designed Grecian Shelter is a peristyle with Corinthian columns. The shelter, completed in 1905, was refurbished in 1966 and added to the National Register of Historic Places in 1972.

William and Lulu Norwood House, September 1, 1958. This nearly 5,000 square foot home was constructed in 1906 for real estate broker William Norwood and his wife. A number of architectural features present a Northern Italian Villa style, including the porch, tower, and the deep eaves (or part of the roof that overhangs the edge of the building). The rest of the home is a solid Colonial Revival. Despite the large home, the oddly- shaped lot has almost no backyard space as the subway (today's Q train) runs directly behind it and the rail infrastructure was present prior to the home's construction.

Adjacent to the Q train tracks, you might spy a clearing in the woods. The Knickerbocker Field Club was established in 1889 in the Flatbush neighborhood of Brooklyn. Its original structure was a two story Colonial Revival Style building clad in clapboard and shingles, with a deep porch supported by Doric order columns. A fire in 1988 destroyed a portion of the building. The Field Club was the last standing portion of the area's Tennis Court development, yet was not considered worthy of landmark status. The remains of the original structure were demolished in 1992, replaced by a new clubhouse, still operating under the name "Knickerbocker Field Club."

St. Paul’s Church in the Village of Flatbush, June 4, 1961. The present St. Paul’s, a Gothic structure dating to 1877, replaced the wooden 1836 church, termed “a neat and handsome edifice” in Peter Ross’s 1902 “History of Long Island.”
