Arco Británico, Memorial arch at Avenida Brasil, Valparaíso, Chile.

Arco Británico is a memorial arch on Avenida Brasil in Valparaíso, designed by the architect Alfredo Azancot and unveiled in 1911. It is clad in marble brought from Italy and topped by a British Victorian lion. Medallions on the arch carry the effigies of Thomas Cochrane, Bernardo O'Higgins, Robert Simpson and Jorge O'Brien, and the coats of arms of Chile and the United Kingdom are also displayed.

The British community of Valparaíso donated the arch to the city in 1910 for the centenary of Chilean independence, and it was unveiled in 1911. It was designed by the French architect Alfredo Azancot. The monument honours four Britons who fought in the Chilean War of Independence: Thomas Cochrane, Bernardo O'Higgins, Robert Simpson and Jorge O'Brien.

The four medallions on the arch carry the effigies of Thomas Cochrane, Bernardo O'Higgins, Robert Simpson and Jorge O'Brien, all linked to the Chilean War of Independence. O'Higgins was Chilean, born in Chillán, while Cochrane, Simpson and O'Brien were British. The Chilean and United Kingdom coats of arms also appear on the monument.

The monument stands easily accessible on Avenida Brasil and can be visited on foot to view the arch and its details up close. Morning or early afternoon visits offer the best light for photos and a clearer view of the stone carvings.

Queen Elizabeth II visited the monument during her official trip to Chile in 1968, and Prince Charles came to see it in 2009. These royal visits show that the monument remains important to the British crown and the relationship between the two nations.
