The Prague Castle complex, which sits on the top of the hill above the city, dominates the skyline, and houses multiple palaces, churches, halls, and museums. The crown jewel of the complex is St. Vitus Cathedral. Construction of this Gothic and neo-Gothic masterpiece began in 1344 and took nearly six centuries to complete. The largest and most important church in Prague, which is surrounded by smaller chapels, is also the spiritual heart of the city. Bohemian and Czech kings and queens have been coronated here and are also laid to rest here underneath the cathedral. The exterior with its heavy bronze doors and carved stone is massive and imposing, but once you enter, the soaring Gothic ceiling overwhelms you with a feeling of lightness. The interior is filled with golden sunlight and glowing colors from the stained glass windows, designed by prominent 20th-century Czech artists, including art nouveau master Alphonse Mucha.
