Flatlands Reformed Church Cemetery, 1922. The Flatlands Reformed Church, along with the Old First Reformed Church in Park Slope and the Flatbush Reformed Church, were founded in 1654. They are the oldest churches in Brooklyn. The church graveyard was established at the same time and it is the resting place of generations of Brooklyn's founding families with names like Lott, Schenck, Kouwenhoven, and Wyckoff. The remains of Pieter Claesen Wyckoff, a church founder, are said to be buried under the pulpit. As Wyckoff died in 1694 and the current building was only erected in 1848, it is unclear where exactly "beneath the pulpit" means. Both the church and graveyard were designated landmarks in 1966.

"Flatbush Ave., west side, between Aves., M. and P. The view shows the old St. Thomas Aquinas R.C. Church, 1931." This small church building opened in 1885 as the mission church of the larger nearby Holy Cross Church. The surrounding area was still very rural, dotted with family farms. By 1901 the parish had 150 members, but with the development and urbanization of the borough happening quickly, by 1909 the parishioners numbered 700. The church functions were moved out of this building in 1930, when a larger church was completed on Hendrickson Street. For a time this building served as a gymnasium for the parish school, but services returned in the 1940s and continue today.
