[1] Operating from 1699 to the early 1800s, the market sold meat, country produce and fish under its covered roofs.
[2][3][4][5][6] The land on which the market was held was originally a salt marsh with a brook.
[2] Fly Market Slip was an extension of the market into the East River, beginning at the end of the road now known as Maiden Lane, between Pearl and South Streets.
The original slip was filled to South Street about 1820 and was made part of Maiden Lane in 1824.
It comes from the Dutch vly, meaning a valley or low-lying area.
