People walking through the front pylon of the Karnak temple at Luxor

The sheer size of the Karnak temple at Luxor is incredible, which is not hard to understand, given that multiple pharaohs were involved in the quest to build the temple over a period of time. After the 34 centuries or so, there is a large amount of wear and tear, but repair and reconstruction over the past several decades has made the temple as one of the most visited monuments in Egypt, given its prime location in the city of Luxor.
In this photo, you can see tourists walking through the front entrance of the temple, and there are a large number of tourists as you can see.
