"Sanssouci Park is the best thing to see in Potsdam, bar none. Strolling through this fabulously landscaped 741-acre green space is like going back to a time long ago, when powerful monarchies still dotted the continent. You'll see a number of 18th-century palaces along with magnificent fountains, well-manicured gardens, and more than 1,000 sculptures. You can’t miss Sanssouci Palace, Frederick the Great’s striking yellow summer home, with its beautiful terraced gardens; the baroque Charlottenhof Palace and the imposing Orangery Palace are also well worth a peek, if you've got the time." - Liz Humphreys
