The city of Taxco lies on very rugged terrain and has steep, irregular streets. The streets are also narrow and generally lack sidewalks, making them picturesque but dangerous. Adding to the charm is that most streets are paved with dark stones, adorned with lines, pictures and even murals of white stone. Some of the pictures in the street are from the Zodiac and meant to indicate certain commercial activities in times past. One example of this is the sign of Taurus near the Church of Santa Prisca, which used to indicate the area of butcher shops. Buildings in the city typically have Spanish-style, red-tile roofs.
