Monumento a la Constitución de 1812, Colonial memorial column in Comayagua, Honduras.

The Monumento a la Constitución de 1812, known as La Picota, is a stone obelisk-like column erected in 1813 on the Plaza de la Merced, in front of the Iglesia de la Merced. It was the last colonial construction in Comayagua and marks the transition to republicanism.

Built in 1813, the monument was the last colonial construction in Comayagua. Captain Juan Nepomuceno Fernández Lindo y Zelaya, later president of El Salvador and Honduras, funded the column to commemorate the open cabildo of 9 October 1812, when Comayagua swore the Constitution of Cádiz. It was declared a National Monument on 11 October 1972.

Locals call the column "La Picota". It was raised after the open cabildo of 9 October 1812, when Comayagua's residents and authorities swore the Cádiz Constitution, and the Cortes decree of 14 August 1812 ordered the main square of every town to be renamed Plaza de la Constitución with a commemorative slab.

The column stands in its original spot on the Plaza de la Merced, facing the Church of La Merced, the oldest church in Honduras, in Comayagua's historic centre. The square and column were restored in 2000 under the Spanish Cooperation's Master Plan for the Historic Centre, so the area is walkable and the monument is seen on foot.

The monument is one of only two columns of its kind from that era still standing in Latin America; the other is in St. Augustine, Florida. It was declared a National Monument on 11 October 1972. A 1820 watercolour of the column is kept in the Archivo General de Indias in Seville.
