The name of this waterfront market, with its iconic four-turreted structure at its southwestern end, comes from colonial times, when the Portuguese would ver o peso (check the weight) of merchandise in order to impose taxes. The display of fruit, animals, medicinal plants and more is fascinating; go early to see fishing boats unloading their catch.

　　Some stands sell souvenirs, but be alert for pickpockets and avoid going after 5pm.
