Kasthamandap is the building that gave Kathmandu its name. The name Kasthamandap means House of Wood. Although its history is uncertain, it was possibly constructed around the 12th century. A legend relates that the whole building was constructed with the wood from a single sal tree. At first it was a community center where visitors gathered before major ceremonies, but later it was converted to a temple. The squat, medieval-looking building is busy in the early morning hours when porters sit here waiting for customers. Kathmandu's Durbar Square was where the city's kings were once crowned and legitmised, and from where they ruled. Rebuilt over the generations, most of the square dates from the 17th and 18th centuries. The king no longer lives in the Hanuman Dhoka (old Royal Palace) in Kathmandu. The palace was moved north to Narayanhiti about a century ago.
