The tower of the ancient Fenaroli castle still exists, but it was transformed in a bell tower. The rest of the castle was lost, especially in 1906 when the river delta, on which the town is built, collapsed into the lake. The old town centre is quaint and welcoming; during spring and summer there are many balconies covered with colourful flowers. The arch under the bell tower leads into a typical small square. The beauty of the town is enriched by many wonderful frescoes.
