Germany
Built in the Gothic style in 1488, this is Munich's most striking church and has been the city's cathedral since 1821. It boasts onion-domed twin towers and no other buildings in the central city can be taller.
Spain
No, this is not Barcelona's most famous cathedral - that honor goes to Sagrada Familia - but this is Barcelona's huge Gothic cathedral from the 14th century (minus the 19th century facade) which played a significant part in the history of the city.
France
Built in the gothic revival style in the late 1800's this church sits on a hill overlooking the city near the Roman Museum. Take the funicular to get up here (and walk back down). If you take the tour to the roof you'll have an amazing view of the city. The interior is quite impressive.
France
This is a fascinating museum of the charity hospital of Beaune which was founded in 15th century.
