The annual “World Tree of Hope” is being installed this week in the rotunda at City Hall. The tree is decorated with thousands of origami cranes, with notes written on them from children around the world.

A formal celebration of the tree will take place on Dec. 7 at 5:30 p.m. in City Hall. The San Francisco Boys Chorus will perform, followed by a Celebration of Hope with Ed Lee and the Consul General of Japan Jun Yamada. Last but not least, the Sisters of Perpetual Indulgence will bless the tree and lead the audience in its lighting.City Hallholidaysorigami cranesworld tree of hope
