The formal entrance into the city of Ek Balam was through this portal arch. The city itself was surrounded by three rings of defensive walls, portions of which can be seen in the right of the top photo.
The portal arch is quite unusual in that it is a perfect square if looked at from above. There is an archway on each of the four sides
An iguana with attitude suns himself near the Ek Balam portal arch. He has an impressive profile.
