Exercise 3 - Original, restored or reconstructed? (sample answer)

Matthias Church: medieval in origin, used as a mosque under the Ottomans, and
mostly rebuilt in Gothic Revival style in the late 19th century. So: partly
original, largely restored and reinterpreted. It matters because the
"medieval" look is a 19th-century idea of the Middle Ages.
Székesfehérvár: the coronation church survives as ruins; the rest is memorial.
Visegrád: ruined, excavated and partly reconstructed from the plan.
Any one, with a clear reason, is a good answer.
