UNESCO's World Heritage Committee decided Tuesday to remove the church and nearby pilgrimage route from its list of significant places under threat because of the "high quality of work" on its leaky roof, broken windows, damaged columns and grime-covered mosaics.
One of Christianity's most sacred shrines, the church was built in the 4th century over a cave where the Virgin Mary is said to have given birth. The Holy Land site also includes several other churches.
The Palestinian Authority launched the renovation after UNESCO put the site on the endangered list in 2012. Bethlehem hopes the renovation will boost tourism and a weak economy in the Israeli-occupied West Bank.
