View of one of the lookout towers in the National Zoological Gardens in Pretoria, South Africa. This lookout tower is situated on the ridge at the back of the zoo. The building in the left of the photo is where the zoo's cable car enters and exits. Normally you would go up on the ridge in the cable car and then walk down to the bottom of the zoo. The high wall from the lookout tower to the bottom is the division between the lion and tiger enclosures. I stand to be corrected but I think the original zoo was built before the 1900's
