The Colón Theater opened on October 27, 1892 to commemorate the 400th anniversary of the arrival of Christopher Columbus to America, and was reopened in July 2014 after a renovation that began in 2008. The restoration of the front curtain, which features "dolls" or "monkeys" drawn on a nineteenth-century linen cloth, was an important part of this renovation.
