Juanita the mummy is well worth a visit. She's over 400 years old, but doesn't look a day over 90!
Sit through the National Geographic documentary beforehand: it's very informative.
Just up the road is Convento de Santa Catalina. It's a small village within Arequipa where the nuns live. The vibrant building colours make it a must.
Both close to Plaza de Armas
