Plazas are the heart and soul of bustling Mexican cities and sleepy desert pueblos alike. Renowned architect Bob Vint travels with host David Yetman to explore a range of plazas, from pre-Hispanic to modern, and examine their unifying characteristics. The program includes a sampling of cities with some of the most beautiful and influential plazas, from the first pre-Hispanic plazas in Chichen Itza to one of the world's largest plazas in Mexico City. Then it's on to the small town of Potscurro to discover how courtyards are to the home as plazas are to the town. The program also uncovers how plazas were valued and used by people in the New World thousands of years before Spanish contact.
