The history of Europe is filled with epic battles, brave campaigns, and tales of warriors performing heroic deeds. And for every warrior who took up a blade, there was a city that needed a way to defend itself. That's why so many of the continent's historic cities are ringed by fortress walls, and many times, architectural gems like fortress gates. This particular gate was built in the 15th century as a way to let people out of the city of Vilnius so they could trade with Medininkai Castle, and farther lands. It was also designed to keep undesireables out. It is the only one of the city's gates still standing. Perhaps it is protected by the fact that a chapel has been constructed above the portal. The chapel is a popular tourist destination because it is the home of the "White Madonna" – a Renaissance-era painting that is said to possess healing power.
