The Monument to the Discoverers or 400th Anniversary Column (Spanish: Monumento a los descubridores or Columna del IV Centenario)[1] is an instance of public art in Palos de la Frontera, Spain.

By 1892, the Provincial Deputation of Huelva tasked Ricardo Velázquez Bosco with the erection of a monument to Columbus and the explorers of the Americas on a plot formerly owned by the House of Alba near the friary of La Rábida.

The original project consisted of a multi-body hexagonal pedestal, which served as the base of a column, topped by an Earth globe.

[5] A new restoration, intending to consolidate the monument by installing a core of reinforced concrete, also recovering elements of the original work, such as an Earth orb or a crown, took place in the 2010s.

[8] Three buried sculpted heads of native americans (reportedly representing the aztec, maya and taíno civilizations) part of the original monument were found out by 2011 during the disassembly of the column.
