16 pound cannon adjacent to the front of Alamo Church that sits on a replica of the carriage

This iconic 16-pound cannon from the Battle of the Alamo is on display outside the Long Barrack. It is mounted on a hand-made replica of an 1800's style carriage that resembles the one that would have been used during the battle in 1836.

The cannon was disabled and buried by the Mexican Army after the battle. Years later, it was discovered by the Maverick Family and later given to the Alamo.

Cannon History
Spanish soldiers saved this 18th century cannon from a shipwreck in Matagorda Bay off of the Texas coast in 1817. It was brought to San Antonio where it was later captured by Texian forces during the Siege and Battle of Bexar in 1835. The following year, the Texians used the cannon at the Battle of the Alamo. It was found buried near the present day intersection of Houston and Alamo streets.

Cannon Conservation

Conservation experts at Texas A&M University have restored the  Alamo's cannon.

In 2017, Alamo Trust, Inc. and Texas A&M University's Conservation Research Lab began restoring the Alamo cannon. Conservationists carefully removed decades of rust and dirt, then applied a tough, non-corrosive coating to protect the cannon from the elements and preserve them for future generations.

Replica Carriage

A new, custom-made trunnion collar designed for the Alamo's 16 pounder cannon.

The carriage is seven feet wide with wheels 66 inches tall. It weighs nearly 1,600 pounds, which is appropriate considering the cannon itself weighs 2,240 pounds!

The carriage designer, Michael Elledge, has made over 100 cannon carriages. The 16-pounder marked the first time his team had to create a custom trunnion collar, since the Mexican Army cut off the original trunnions after the battle in 1836.

Why is it blue? Based on old Spanish manuals from the time, the carriage would have originally been painted cobalt blue. By the time of the Battle of the Alamo in 1836, it would have faded to a sky blue.
