Gatehouses
The most visible remnants of Manhattan's
portion of the Old Croton Aqueduct, outside of Highbridge
Park, are three gatehouses. These regulated water
flow and provided maintenance access to the aqueduct
tunnel.
The gatehouses are located at:
•
135th Street/Amsterdam Avenue
near Convent Avenue (southwest corner)
•
119th Street/Amsterdam Avenue
(southeast corner)
•
113th Street/Amsterdam Avenue
(southwest corner)
