The Museo del Mar Lord Cochrane was built in 1842 for the dashing Scottish naval hero Lord Thomas Cochrane (who set up Chile's navy), but was never occupied by him. The building, a tile-roofed, colonial-style house above Plaza Sotomayor, held Chile's first astronomical observatory. There are few exhibits, but the patio has a stunning view over the harbor. To reach it take the Ascensor Cordillera (located one block north of Plaza Sotomayor) to Cerro Cordillera, then walk east to Merlet at the top of the ascensor .
