The Alamo was surprisingly GORGEOUS. I wasn't able to go through a tour since we arrived in downtown San Antonio so late, but the outside was more than enough eye candy for me. I love the cleanness of the structure with the little 'tszuj' of an ornate entrance.
And the weathering on the stone? I mean, come on. Can you get any prettier???
This little church right around the corner was a beauty, as well. Throw in a little River Walk and you have one aesthetically pleasing night!
