Castdllo Principesco, being small and cute, fits perfectly in the town of Merano. It was refurbished in the 19th century, furnished with period furniture and paintings, to give a good idea of what life here must have been like in the 1500s. The frescos on the walls are clearly visible, as are the patterns on the floor tiles (although the heavily worn spots attest to the age and heavy use it has seen).
This is not one of Europe's major chateau, with hundreds of rooms, impressive long galleries, and huge chandeliers. It's much more comprehensible! We spend a fine hour or so inside, and really felt like we learned all there was to know. The fellow selling tic,ets was most helpful. Although he could not leave his booth at the entrance, he gave us a printed English-language description of the rooms, and answered all the many questions we had as we left.
We qualified for the over-60 discount, but even at the full price of €2 I would have found the time and money well spent.
