Barcelona's Sagrada Familia basilica hits peak height

Constructors crowned the largest tower of Barcelona's unfinished Sagrada Familia basilica with a final piece on Friday, setting the peak of the world's tallest church at 172.5 metres.  Completion of the entire Sagrada Familia, however, is expected to be completed in around a decade's time.

The tower milestone comes more than 140 years after famed Catalan architect Antoni Gaudi designed the monument that has become a symbol of Spain's second city and a globally renowned tourist attraction. The extra height now atop the Jesus Christ tower means the Barcelona basilica now surpasses Ulm Minster in Germany as the world's tallest church.
