So, while I was living in Mexico, I used to highly enjoy going on what my dad and I called our Sacbe (Mayan term which means "white road", a Sacbe tended to connect one city to another in the pre-Columbian Yucatan peninsula), which was going to Mayan archaeological sites, climbing pyramids, etc. One striking feature of Mayan architecture was the so called "Mayan false arch", a variant of corbel arch. It was quite common to see them on buildings all throughout the Mayan regions, but Yucatan had a particular tendency to have arches (much in the fashion of those in Rome) along their Sacbes, often indicating their beginning or end. Thus, the inspiration for this model.
Built circa 2004.
An actual Mayan Arch (from the House of the Doves in Uxmal, also featuring similar masonry)
