The Plaza Sotomayor is dominated by the impressive blue-colored palatial Edificio de la Comandancia Naval (Naval Command Building). In the middle of the square lies the Monumento a los Héroes de Iquique , a subterranean mausoleum paying tribute to Chile's naval martyrs.
The Aduana Nacional (Customs House) and Estación Puerto, the terminal for Merval commuter trains, are also nearby. The plaza has a helpful tourist kiosk and a tacky handicrafts market, the Feria de Artesanía. Muelle Prat , the pier at the foot of Plaza Sotomayor, is a lively place on weekends, and is the prime point for crane- and container-spotting.
