The Maine Avenue Fish Market of Washington, D.C., also known as "the Wharf" or "the Fish Wharf", is one of the few surviving open air seafood markets on the east coast. In operation since 1805, it is the oldest continuously operating fish market in the United States. The Maine Avenue Market was relocated in the 1960s, within a few blocks of its original location on the Washington Channel...Located on the Southwest waterfront under the shadow of Interstate 395, it stands as a cultural relic popular with locals but unknown to many of the tourists who flock to the monuments and museums just five blocks north. There are over ten stores, each with a specialty. The Maine Avenue Fish Market is open each day of the week, but the largest selection of fish is on display Friday evening through Sunday.
