The two-towered Castillo de Santa Bárbara was originally built as a watchtower to observe both the north and the south coast, it was used to scan the seas for pillaging pirates. Since 1991 the castle houses the Museo del Emigrante Canario (Emigrant Museum), which tells of inspiring, sometimes also very tragic, stories of Canary Islanders, who – in search of a better life and to escape death of hunger on their native islands – emigrated in masses to South and Central America.
