SOURCE 

Hey im responding to the source of the sanjacinto monument fact i wrote down, so here are a few http://www.sanjacinto-museum.org/About_Us/Media_Kit/Fact_Sheet/, also http://www.sanjacinto-museum.org/Monument_and_Museum/. On both links you can find the information stating it as the worlds tallest monument tower and worlds tallest masonary tower.
