12 p.m. | Old Town Square
It can be easy to lose track of time while souvenir shopping, so make sure to keep an eye on the clock! Head to Old Town Square to see the whimsical Prague Astronomical Clock. Constructed in 1410, this is the oldest operating clock in the world. Once an hour, you’re in for a treat when the colourful medieval clock comes alive with chimes and ornate moving parts and symbols, like the parade of the Twelve Apostles.
2 p.m. | Prague Castle
Home to the president of the Czech Republic and permanent keeper of the Bohemian Crown Jewels, Prague Castle is the largest ancient castle in the world, so prepare to be overwhelmed. You’d need a full day to see everything, but if pressed for time, look for St. Vitus Cathedral, where the crown jewels are stored under lock and key. Be sure to also check out St. George’s Basilica, Lobkowicz Palace, the 1.6-hectare horticultural gardens, and Golden Lane, where the servants and goldsmiths lived.
