A short walk uphill from Plaza de Armas is another small plaza, Plazoleta Nazarenas. There are a few historic buildings around the square that have been refurbished for modern uses.
One of those buildings is a mansion built in 1850 by the Earl of Cabrera. Before that, in 1580, it was the mansion of Alonso Díaz, a Spanish conquistador. It was built over the Inca ceremonial court of Kancha Inca. Today, the building houses the Museo de Arte Precolombino. It’s open daily from 9am to 10pm. Admission is S/20.
Another important building on Plazoleta Nazarenas is the former Seminario de San Antonio Abad. Built in 1592, it’s now a luxury hotel. The Capilla de San Antonio Abad is still a working chapel and was built in 1678.
Finally, there’s the Palacio Nazarenas, which is now an exclusive boutique hotel.
Follow the road downhill one block south from Plazoleta Nazarenas and you will come to the Palacio Arzobispal (Archbishop’s Palace). Inside is the Museo de Arte Religioso, where you can find priceless works of religious art. Honestly, the museum part was a little disappointing. Admission to the palace is included in the Boleto Integral.
The Palacio Arzobispal was built on top of the Inca Roca Palace and features many interesting stones. You can admire them walking along Calle Hatunrumiyoc. The street is named for one of the most famous Inca sites in Cusco, a unique 12-sided stone built into the palace called Hatunrumiyoc. It displays Inca architectural ingenuity.
A block west of Plazoleta Nazarenas, back towards Plaza de Armas, is a school with a fountain in front, Colegio Real San Francisco de Borja. It was a Spanish colonial school that specialized in the education of Inca nobles.
If you climb the wall with the fence on top, you will get a great view of Plaza de Armas. Follow the path along the wall for even more great views.
Across from the school is the Museo Inka, housed in the former Palacio del Almirante. It was one of the best examples of a colonial home in Cusco and was built on top of Inca foundations. The museum is one of the most spectacular in Peru and a must-see when visiting Cusco. The collection starts out a bit slow with too much pottery, but once you get up to the second floor, you will find an incredible collection of artifacts and displays about Inca history. Admission is S/10.
