In the A Song of Ice and Fire novels, there is a Ragman's Harbor. It's one of two harbors in Braavos, the other one is Purple Harbor, which only serves the locals. Ragman's Harbor is poorer, dirtier, and noisier than the Purple Harbor. It's were foreign ships are berthed. Many people make their living around Ragman's Harbor, including porters, mummers, ropemakers, sailmenders, taverners, brewers, bakers, beggars, and whores.
