Actually, the Alamo was left in ruins after the Texas Revolution until around 1850 when the US Army began repairs. It was then that the gabled roof and "hump" were added. For some great info on the Alamo, go to the Daughters of the Republic of Texas site at http://thealamo.org/ . My 1st cousin 5X removed through marriage was William Barret Travis, the commander at the battle of the Alamo. He married Rosanna Cato (my 1st cousin 5x removed). Teri
