Itumbaha, one of the five principal monasteries of Kathmandu, is one such worthy site not only for its ritual importance in Newar Buddhism, but also for its wealth of early woodcarvings and architectural configuration, largely intact from the 13th century. Itumbaha preserves its original two story configuration and roof form as well as numerous building components including carved windows, pillars, and roof struts from the 13th century. The courtyard is dotted with additional votive structures, some of great artistic importance such as the 17th century caturmukhi caitya (lit. four faced stupa).
