Zurich is Switzerland's largest city. It is situated in the north central part of the country, not far from the border with Bavaria, Germany. It lies at the end of Lake Zurich, which extends 40 km (about 25 mi) to its southeast. Contributor Iris Films used a DJI Mavic Pro drone to shoot this beautiful aerial video of the city, which includes overhead footage of the city's historic churches in Old Town and its well known Opera House. The city is over 2,000 years old, having been founded by the Roman Republic.
