Prague III -- St. Vitus Cathredral

 St. Vitus dominates the Prague skyline, and is by far the largest building inside the castle complex.
It's a real tribute to perseverance:  started in 1377 and finished in 1929.

The Charles Bridge, also from the same era.  Started in 1357, it only took 45 years to complete.

Some of the pipes by the console.

The nave --

-- stained glass windows --
