Outside its lively February carnival season, Solsona, 20km northwest of Cardona, is a quiet experience. That said, within the pretty old town, you'll discover a scattering of historical structures including fragments of medieval walls, a 16th-century clock tower, an early Romanesque cathedral, and three Gothic fountains.
The high point of Solsona's Carnaval used to be the hoisting of a donkey by its neck up the bell tower, hence the nickname matarucs (donkey killers) for local people. The tradition remains, although nowadays the donkey is a water-spraying fake. Beyond the donkey-dangling, Solsona's festivities are renowned for their impressive gegants (giants), oversized human models that assume pride of place.
