AP reports that in St. Petersburg, Russia, competing demonstrations were staged yesterday over the city's decision, announced last month, to return St. Isaac's Cathedral to the Russian Orthodox Church. The Cathedral was seized after Soviets took control in 1917, and was turned into a museum. It has become one of the city's top tourist attractions. Opponents of the return are concerned that Church tours will begin to focus too much on the Cathedral's religious aspects at the expense of its architectural and cultural importance.
