Every Argentine city has its central square but Salta's is extra special. The myriad native and exotic trees and shrubs provide shade for the city's folk, plus tourists, shoe shines and all manner of other human traffic. To the north stands the gaudy cathedral, which was built in the late 19th century to an Italianate neoclassical design – you can't miss the bright pink exterior. Inside it is decorated with striking frescoes and a number of chapels shelter the city's much prized relics, including the corpse of local hero General Guemes. On the opposite side of the plaza is the Cabildo (colonial HQ), built in the 17th and 18th centuries and heavily restored in the 19th. It is home to the varied collection that is the North's major historical museum, largely comprising old paintings, ancient furniture and elaborate carriages. The upper floor, which affords great views across the plaza, is used for interesting temporary exhibits. The northeast corner is where you'll find the city's excellent modern art museum, the MAC.
