We visited a lithic museum, some Inka ruins, lots of examples of Inka architecture, an Inka pottery kiln, the worlds highest Faculty of Veterinary Science, a pottery, Spanish architecture in the form of churches, more markets, the headwaters of the river Urubamba mentioned in Great-Grandpa's papers and to top it all off a shop selling historic maps.
The latter we found after we checked into our hotel and went for a walk to find a bite to eat. Can't wait to explore Cusco in the daytime.
