Cusco is not limited to Plaza de Armas, Qorikancha, and the churches. The rest of the UNESCO World Heritage listed historic city is well worth discovering. You’ll find many interesting places along the way.
Just to the west of Plaza de Armas is Plaza Regocijo. The Municipalidad de Cusco is located here.
This small plaza seems to have events quite often. One day I passed through and there was a military parade. On another day, I was able to watch live music and see the plaza filled with food tents serving cuy (guinea pig), a Peruvian delicacy.
To the south of the plaza is Avenida El Sol. This is one of the main arteries of Cusco. It connects Plaza de Armas with Qorikancha, the bus terminal, and airport. One of the most prominent buildings along Avenida El Sol is the Palacio de Justicia (Courthouse). At the southern end of it is the Centro Artesenal Cusco, a handicraft market where you can find all kinds of souvenirs including alpaca sweaters.
Even further west is a great place to see how Cusqueños live. The Mercado San Pedro has stalls selling everything from cheese, meat, vegetables, and fruits to souvenirs, clothes, and household goods.
The market spills out onto the streets as well.
