Shrines lined the sides of the Heb Sed Court.
The Heb-Sed is the ritual celebration or jubilee of a king's reign. Normally, it was first held during the 30th regnal year of a king, and from then on, every 3 years.
During the celebrations, the king performed a ritual run and dance, aimed at proving that he was still physically able to rule the country. In doing so, he was also rejuvenated and reborn.
