Here’s our regular weekly post from the Center for the Urban Environment about the great tours they run:

Park Slope South – Southern Exposure. Sunday, June 15 – 3-5 pm – with Matt Postal. Explore Park Slope’s numbered streets, heading south from the Litchfield Villa. Both older and more architecturally varied than the blocks to the north, we will discuss the neighborhood’s rich history. We’ll pass handsome townhouses, impressive schools and religious structures, as well as the Ansonia Clock Factory, which once produced ten thousand timepieces each day. Meet southeast corner Prospect Park West & Third Street. Take the F train to Seventh Avenue, exiting at Eighth Avenue, or the 2/3/4 to Grand Army Plaza and walk south along Prospect Park West.
