Other facilities include a primary and a secondary school, a monastery and the Holy Trinity Theological College, a museum and monuments housing the remains of those massacred in Addis Ababa by the Italians in 1937 in response to an assassination attempt against the Fascist Viceroy of Italian East Africa.
