Once a federal prison housing dangerous and notorious criminals, Alcatraz (The Rock) now welcomes tourists into the cell blocks once occupied by the likes of Al Capone, Machine Gun Kelley, and the Birdman of Alcatraz. Self-guided audio tours have dramatic narratives of Alcatraz’s grim history, including realistic sound effects one would hear in prison. Apart from the prison complex itself, Alcatraz Island essentially operates as a national park. You can spend a full day hiking, taking in the view from multiple observation points and appreciating the natural beauty.

You'll find fewer places more conducive to rest and relaxation than this former convent garden, a green oasis in the centre of Mechelen!

Be prepared to have your mind bent, blown and rewired as you walk into the Lange Voorhout Palace where the illusory work of famous graphic artist M.C. Escher is exhibited. The palace is home to such legendary Escher paintings as 'Air and Water' in which birds are blended into fish and 'Waterfall' in which water appears to flow upwards instead of down. There are interactive experiences on the second floor, dedicated to the Eye of Escher where guests are encouraged to solve some of Escher’s most perplexing mysteries, including the impossible Penrose Triangle. On the third floor, there is a large-scale optical illusion where adults can appear to be children and vice versa. Audio tours and guided tours are available and there are additional temporary exhibitions taking place on occasion.
