Plaza Arturo Prat, Central monument in Iquique, Chile.

Plaza Arturo Prat is a public square in Iquique containing major 19th-century structures, including a prominent clock tower and the city theater building. The plaza is framed by colonial and neoclassical buildings that define its historic character.

The plaza took its current form during the nitrate boom between 1880 and 1920, when mining brought significant wealth to the region. Many of the buildings standing today were built during this period to reflect the city's economic power.

The square is named after Arturo Prat, the Chilean naval commander killed at the Battle of Iquique in 1879, and it was already known as Plaza Prat before the 1880 fire. Around it stand the Torre del Reloj, the Teatro Municipal and the Edificio Sociedad Protectora de Empleados de Tarapacá, alongside the Casino Español and the Club Croata, buildings tied to the nitrate-era social clubs.

The square sits in central Iquique and is easy to reach on foot, with shops, restaurants, and bus stops nearby. Visitors will find outdoor seating and should be aware that the sun can be quite strong in this coastal region.

The plaza and its buildings have survived multiple earthquakes and fires that struck the region, showing the resilience of construction methods from that era. This survival makes the preserved structures rare examples of early 20th-century building techniques along the Chilean coast.
