Known as El Morro, this fortress was designed to protect the city from attacks by sea. In 1983, the United Nations declared the imposing fort a World Heritage Site. Today, it is an interesting museum that offers great views, and it is open for visitors to enjoy and explore.

San Xavier del Bac Mission, located 10 miles south of Tucson on the Tohono O’odham Nation, is an iconic example of Spanish colonial architecture. Known as the “White Dove of the Desert,” its striking white facade contrasts beautifully with the surrounding desert landscape. Built between 1783 and 1787, the mission blends Moorish, Byzantine, and Mexican Renaissance styles, featuring intricate carvings, vibrant murals, and a gilded retable depicting biblical stories. Still an active parish, it holds daily masses and remains a spiritual center for the Tohono O’odham people. Extensive restorations have preserved its historic beauty, making it one of the best-preserved Spanish missions in the U.S. Visitors can explore the mission’s interior, join free docent-led tours, or browse crafts and frybread sold by local artisans.

Emerging from the placid waters just like the nearby National Museum, the National Theatre is one of the biggest theatres in the Arab world. It hosts performances by some of the foremost artists in the world, ranging from classical music and ballet to contemporary shows. The impressive architectural achievement owns much to local tradition with the wooden interiors and the 1,001 seats inspired by the world-famous Arabic tales.

Another must-see attraction is the Chen Ancestral Shrine, which has a history of more than 100 years. The hall was once an ancestral shrine, initially built in 1888 and completed in 1894. Later, it turned to Chen Clan’s Industry College, and today it is home to the Guangdong Folk Arts Museum that exhibits a variety of folk arts and crafts.
