One of the oldest churches and from what I understand, the largest in area-under-roof…read more.. Standing outside this church, you can't be feel in awe - when you go inside, you become slackjawed at the immensity and sheer awe inspiring feel this structure gives off. When you learn how long it took to build this structure - in the order of 600 (or maybe I forget 800 years) - it is a testament to human endurance and persistence. The frescoes, the buttresses, the carvings, the paintings, the everything of this place inspires a tongue-tied, mind-bending, experience. Kinda leave you wondering about your place in this whole wide world... Anyway, tickets are 12 Euros each and it's worth every penny. There is a plaza next to the church where you can start at this enormous and wondrous piece of architecture for about as long as you would like. It was well worth the time spent getting here and the parking hassles that Cologne has to offer...

We came here September 2026. Cost was $12. Get there early…read morewe came at 2 pm and they were closing at 330 for special event. We stayed the whole time. So Quiet and beautiful. This one took 600 years to build but sat vacant for 300 years. Mosaic floor was very impressive. The outsiders black because all of the soot from all the industries over the years. Hard to clean because it is a gummy film. They have to use a special sand to clean it. I still don't know how they built these with no power tools? Loved it! Shopping area and all kinds of restaurants are right next to the cathedral the river is a short walk away.

St. Gereon belongs to one of the 12 renown Romanesque churches in Köln and is my personal favorite…read more Among that elite group, it is also one of the most unique, inspiring, and beautiful. Anyone interested in church architecture needs take the time to see this magnificent structure. Though the church we have today was finished in the 1200s, there has been a Christian house of worship on the site since the 600s. This kind of history beckons worshipers and culture enthusiasts alike. Highlights of the basilica include the dome, which, at one time, was one of the largest domes in Christendom next only to Hagia Sophia in Constantinople. Visits should also take time to marvel at the amazing stained-glass windows through the interior. Whether your going for a Gottesdienst or simply to enjoy the tranquility and beauty of the building itself, St. Gereon is a wonderful site to behold.

Groß St Martin is a lovely church from the 1200s. While it is much more basic than the cathedral,…read moreit is still quite nice and is well worth stopping by as you walk through the old town. The church itself is pretty, but the really impressive part is the excavation Roman ruins in the basement. They aren't huge, but it is a unique experience, and they are well signed and maintained. The church is free, but there is a ,50-cent fee to walk down into the excavation (they have laminated descriptions in four languages, but the signs are in German). Definitely worth the ,50 cents to see the ruins!
