Aztec Hotel

If you think you've driven by some Aztec ruins along Route 66 in the city of Monrovia, California, you might not be too far off base. The Aztec Hotel was built in 1925 and designed with both Aztec and Mayan architecture. It was a hotspot for Route 66 travelers back in the day, but is no longer in business. The Aztec Hotel is still a popular site for passers by and is listed in the National Register of Historic Places.
