…Castle Hill, a UNESCO World Heritage Site (along with the River Danube embankments and the whole of the boulevard Andrássy út).
This is the Matthias Church. I do like to list all the architectural styles because I can never guess .. the 1015 structure was Romanesque, then in the mid-1300s it was rebuilt in ‘the florid late Gothic style’, and extensively restored in the late 19th century.
