Lining the inner reaches of the harbour are rows of low single-storey boathouses, called escars in Catalan — squat stone-and-stucco buildings with arched doorways opening directly onto the water and shallow tiled slipways for hauling boats. They are painted in faded ochres, blues, greens, and pinks, and they make Porto Colom's waterfront unlike anywhere else on Mallorca.
You will see them all along the western shore between the church and the lighthouse promenade. Some have been converted into small houses or studios; many are still actively used by working fishermen, with traps, nets, and outboard motors stacked outside. Walk the entire harbour edge for the best views; about 45 minutes round trip.
