SERGEANTSVILLE is located in the heart of Delaware Township, and serves as its de facto capital. The tavern of former years is now the township municipal building. Except for Perth Amboy’s municipal building, Delaware Township’s is the longest continually used building for municipal government. Being located at the intersection of county routes 523 and 604, it is still a fairly busy place, but nothing like it was in the 19th century, when farmers would come to town to shop and collect their mail.
