E-ninnu

The E-ninnu 𒂍𒐐 (House of 50) was the E (temple) to Ningirsu in Lagash. It was constructed by King Gudea of Lagash in the mid 22nd century BC. The Gudea cylinders, perhaps the longest surviving text written in the Sumerian language, give an mythical account of the building of the temple, along with a description of the rituals and symbols associated with E-ninnu. In Uruk, the temple is also claimed to be built by Ur-Nammu.
