The Tudor-Stuart Garden Apartments. Find the knight!

A closer look reveals a number of other birds, as well as some rat- or weasel-like creatures, interwoven into the ornate patterns surrounding the doorway.

This 53-unit building for low-income and formerly homeless individuals was erected on a long-vacant, oddly shaped lot abutting the tracks of the Q train (aerial view). The interior décor includes Shona stone sculptures, so it seems like a decent bet that the carved birdies pictured here also hail from Zimbabwe.

This sculpture at Prospect Park's Imagination Playground was inspired by Ezra Jack Keats's book Peter's Chair. From the NY Times:

When the playground opened in 1997, the sculpture of Peter was a deep blue. "The ears soon lost their patina," Mr. Zimmerman said, "because kids would sit on the rock and whisper to Peter."

I assumed that this memorial grove in Prospect Park would consist of trees planted around the time of the grove's dedication in 2003, so the scarcity of young trees in the area (you're looking at just about all of them) made me wonder if some others had died and been removed over the past decade. This page leads me to believe that the grove's creation mostly involved the restoration of an existing treed area of the park, however, which makes more sense given the surroundings. You can take a look around the grove here.

Home to the second-highest peak in Brooklyn, this park occupies the former site of the Mount Prospect (or Prospect Hill) reservoir. Here's an early 20th-century postcard view of the reservoir and its water tower.

Of the 45 or so slot car parlors that began springing up in NYC half a century ago, this is the only one left. To learn more about the place and its owner, watch these two videos.
