Quesiton: In which city is this famous tower located?
The answer is: Edinburgh, Scotland
Camera Obscura and the World of Illusions might not look like much compared to other buildings in Edinburgh. However, the major tourist attraction in Scotland is quite mesmerizing on the inside. The historic tower located on Castlehill near Edinburgh Castle became an observatory in 1853 — housing a famous telescope believed to have been made by famous scientific instrument maker, Thomas Short. Visitors came to witness the “best views in the city” until the tower was again transformed into a learning center.
