The centre of Cusco was the Arms Square (every conquered city had a Arms Square). The Inca palaces were converted into churches by the Spanish. However, the streets around the Arms Square were well preserved as cobweb streets. The streets around the Arms Square lasted more than an hour. The ancient city was built on the hillside, with a little breathing up and down, and some alleys. Zi Zi was too dark to go in (cover his face) and the scattered street layout was really delicious (snickering). You can imagine how brilliant the Inca Empire was.
