Admire the gorgeous Gothic interior of Cologne Cathedral.

#EuropeanTravel How to get there: Domkloster 4, 50667 Köln, Germany Attraction: Cologne Cathedral I carefully looked around the interior of Cologne Cathedral, which many art historians call a Gothic treasure. First of all, the stained glass that filled the cathedral caught my eye. I also saw various sculptures on the walls!☺️ This building, which is considered one of the world's must-see buildings before you die, is said to have 20,000 visitors a day. Plus, admission is free, so there's no reason not to visit!👍 #CologneCathedral #CologneTravel
