Philadelphia's City Hall tower has reopened to tours following its closure on Sept. 22 because a crack was discoverd in the structure.

The tours resumed last week, but the announcement apparently was lost in the stir surrounding the ouster of the Occupy Phialdelphia encampment from City Hall's Dilworth Plaza.

The tower and its obervation deck were closed to tours on Sept. 22 after a crack was discovered on its north side. The crack may have been caused by the earthquake that rocked the East Coast a month earlier.

During the repair project, Occupy Philadelphia protesters did move part of their encampment to allow a crane in to work on the tower.

At 548 feet in height, the tower is the tallest load-bearing masonry structure in the world.

For tours and tower admission go to Room 121 at City Hall or call (215) 686-2840.
