The Mision San Antonio de Valero, now known as the Alamo, was constructed in 1724 and served as a residence for missionaries and Native American converts for almost seventy years...until Spanish officials took over the property and parceled out the land in 1793. By the early 1800's, the Alamo was a station for the Spanish cavalry unit and remained a military base until the Texas Revolution...but by this time it had fallen into disrepair.
