The Old Market Plaza is the original market square of colonial Roseau, a cobbled triangle of land beside the Dominica Museum. The market function has long since moved to the larger New Market by the river, and the plaza is now a daily craft fair selling Kalinago basketry, hot sauce, vetiver soap, and the usual cruise-passenger souvenirs.
A small monument in the corner commemorates its earlier use as a slave market. The whole space, surrounded by a few of the older stone-and-timber buildings in town, gives the best sense of what colonial Roseau once looked like.
