German police say a World War II bomb has been found outside the 18th century Residence Palace in the city of Wuerzburg. Experts have determined that it is no longer dangerous.

Police say the roughly 550-pound bomb was unearthed Monday during construction work in a square outside the palace.

A police statement says experts determined that the bomb was no longer functional. They still planned to remove it from the site.

The palace is a UNESCO world heritage site and a popular tourist attraction in the Bavarian city. It is known for its staircase with frescoes by the Venetian artist Giovanni Battista Tiepolo.

Unexploded bombs from World War II are still found regularly in Germany more than 60 years after the conflict's end.
