“Urbs Ierusalem Beata”: The Hymn for Evening Prayer for the Dedication of a Church
The hymn “Urbs Ierusalem beata” (Blessed city, Jerusalem), by an unknown author, is from the eighth or ninth century at the latest. The Liturgy of the Hours as revised by Pope Paul VI, consistent with the tradition, has assigned it to Evening Prayer for the anniversary of the dedication of a church.
