You should see the Alamo in downtown San Antonio. ~1/4 (maybe an acre of land) of the original fort is preserved as a park along with the chapel. Santa Anna leveled the rest of the fort (I think). The rest of the battlefield is under city streets, buildings, and parking lots. But I defy you to find a more solemn shrine to sacrifice anywhere. The amount of land we set aside to preserve the memory has nothing to do with preserving the memory.
I’ve seen the Alamo, and know what your saying. I was stunned the first time I visited.
