The front side, on which Ross Burns has: "As you approach from the south entrance to the temple, the steps are flanked by two carved lions, a common Hittite theme continued on the frieze of lions and sphinxes that runs across the lower façade and vestibule. Note the three huge footprints (each 1 m long) [I managed to see them but not take the picture] carved into the paving of the entrance as if left by some giant extra-terrestrial visitor. A fourth is carved on the threshold of main hall." I confess to not taking a picture of the giant prints.
