Time Out says
The world-record-holding largest castle complex in the world and seat of the Czech president
The Prague Castle silhouette is dominated by the Gothic St Vitus Cathedral, whose stained glass windows (including one by Alphons Mucha) are worth stepping inside to admire. Guided tours are available to walk guests through individual rooms, but a free solo stroll throughout the grounds is often just as satisfying. The tiny houses of Golden Lane, Romanesque façade of St. George’s Basilica, and the manicured landscapes of the South Gardens are a few favorite stops along the way. A changing of the castle guards at the gates takes place daily at noon. Exploring every corner of these massive fortified grounds would take an entire trip, so read up in advance to choose your interests.
Time Out tip: Security at the gates is tight and the lines get longer as the day drags on. Leave any large bags behind and arrive early for a less stressful experience.
