Puma Punku, is part of the Tiahuanacu complex, found near the city of La Paz. It seems to be the remains of a wharf, since Lake Titicaca seems to have extended beyond it's current limits. There is little to see but large stones on ground but a massive, four-part, now collapsed building. One of the construction blocks from which the pier seems to have been made weighs an estimated 440 tons and several other blocks laying about are between 100 and 150 tons
. The quarry for these giant blocks seems to have been on the western shore of Titicaca, some ten miles away, certainly a long distance to transport these huge rocks.
