3 Best Sights in Outside the Plaza, Santa Fe

Believed to be the oldest church still in use in the United States, this simple earth-hewn adobe structure was built around 1610 by the Tlaxcalan Indians of Mexico, who came to New Mexico as servants of the Spanish. Badly damaged in the 1680 Pueblo Revolt, the structure was restored and enlarged in 1710. On display in the chapel are priceless statues and paintings and the San José Bell, weighing nearly 800 pounds, which is believed to have been cast in Spain in 1356. In winter the church sometimes closes before its official closing hour. Latin mass is held daily at 2 pm, and new mass is on Sunday at 5 pm.

The symbol of the Zía Pueblo, which represents the Circle of Life, was the inspiration for the state's capitol building, also known as the Roundhouse. Doorways at opposing sides of the 1966 structure symbolize the four times of day, the four directions, the four stages of life, and the four seasons. Take time to walk through the building to see the outstanding 600-work collection of the Capitol Art Foundation, historical and cultural displays, and handcrafted furniture—it's a superb and somewhat overlooked array of fine art. The Governor's Gallery hosts temporary exhibits. Six acres of imaginatively landscaped gardens shelter outstanding sculptures.

Also called the DeVargas Street House, this adobe dwelling is said to be the oldest in the United States—a sign on the exterior puts the date at 1646. Some say it's much older, but historians currently can verify only that it dates back to the mid-1700s. Inside the tiny museum, a small gift shop features Harvey House jewelry, kachinas, paintings, pottery, and more.
