Let us now leave Town Square and wend our way along Leyden Street, so named in 1823, originally called First Street and later Great and Broad Street. On the right as we move easterly toward the water we see, on the site of the Elder Brewster homestead, the new Federal Building, in which is located the Customs House and Post Office. This is on the corner of Leyden Street and Main Street Extension, the latter extending over Town Brook referred to in Bradford’s History as “a very sweete brooke,” and which runs parallel with Leyden Street, emptying into the harbor just below.
