The next is San Marcos, founded in 1604 and once home to natives of Tlaxcala state who fled persecution. Today, the area hosts the traditional San Marcos Fair in springtime. There is San Marcos Gardens, a charming green spot where paths and trees are abundant. The gardens are traditionally frequented by poets, artists and lovers on lazy afternoons. Directly in front of the gardens, you'll see the baroque San Marcos Temple, its tiled dome glinting in the sun.
