They couldn’t save Ebbets Field, but an important piece of Brooklyn Dodgers history is now being protected.

Con Edison is preserving part of a 20-foot-high stone wall on Third Avenue near First Street in Gowanus that was once part of Washington Park — an early home to the Dodgers before the club moved in 1913 to Ebbets Field.

The 18,000-seat park opened in 1898 and hosted the Dodgers until 1912. The Brooklyn Tip-Tops of the Federal League also played there from 1914 to 1915. Most of the park was demolished in the early 1920s.

The remaining wall is now part of a Con Edison truck depot. It is a 30-yard-wide section that was near the park’s back entrance.
