Hotepsekhemwy
A new royal residence called "Horus the shining star" built for Hotepsekhemwy. He also built a temple near Buto for the god Netjer-Achty and founded the "Chapel of the White Crown". The white crown, the hedjet, is a symbol of Upper Egypt. This is a clue to the origin of Hotepsekhemwy's dynasty, and shows a likely source of political power. There is no mention of a Sed festival,which shows that Hotepsekhemwy cannot have ruled longer than 30 years. The Sed festival was celebrated as the anniversary for a reign of 30 years.
