Three Ways of Looking at Park Slope: Park Slope Northwest

This is the first of three tours (others to follow in 2010) looking at
different areas of Park Slope and aspects of the neighborhood’s
history. The first walk looks at Park Slope’s western edge and its
relation to the Gowanus Canal. We will discuss the history of the canal
and its bridges, cross over for a brief peek at Carroll Gardens, and
return to touch down in the Park Slope Historic District. Leader: Francis Morrone,
architectural historian. Meet in front of the Old Stone House in J.J.
Byrne Park, just off 3rd St. between Fourth and Fifth avenues.
(Transit: R train to Union St. and walk south on Fourth Ave. six
blocks; F train to Fourth Ave. and 9th St. and walk north on Fourth
Ave. six blocks). $15, $10 MAS members. Reservations and prepayment
recommended. Call 212-935-2075.http://mas.org/tours/#threeways
