Where in the World???

 Actually, it's quite easy.  It's East Kilbride, in Scotland.

Or , more likely San Giorgio Maggiore (church), Venice.   A 16th-century Benedictine church on the island of the same name in Venice, northern Italy, designed by Andrea Palladio, and built between 1566 and 1610. The church is a basilica in the classical Renaissance style and its brilliant white marble gleams above the blue water of the lagoon opposite the Piazzetta di San Marco and forms the focal point of the view from every part of the Riva degli Schiavoni.
