Kassel's main parish church was built in Gothic style between 1364 and 1462, but in 1524 it changed from Catholic to Protestant denomination; surely a frustrating event for the Catholics who spent 98 years building the thing. Much of the church was destroyed in 1943, and in the 1950s it was rebuilt with quite elegant modern interior elements and two slightly oversized new towers that nevertheless are now landmarks for the city. The man highlight inside is the 12-metre-high grave of Landgraf Phillip, an unusual mix of Renaissence and Baroque styles; this was walled in during the war and survived the bombing. There are regular organ concerts, so keep an eye on the schedule.
