A few kilometres from Viterbo, on a tuff plateau, is Arlena di Castro, a rural centre with 16th-century architecture dating back to the Farnese domination.
At 120 km from Rome, the village was refounded in the second half of the 16th century by Cardinal Alessandro Farnese, Duke of Castro. Do not miss the Collegiate church, the Church of San Rocco, the Chapel of Santo Sepolcro and the Church of San Giovanni. Going further south, one can see remains of Etruscan tombs, clay fragments and the ruins of a medieval castle, including a four-meter high tower surrounded by imposing walls.
Nearby, the characteristic town of Tuscania is ideal for nature walks in Torre di Lavello Park, and cultural visits to the churches of San Pietro and Santa Maria Maggiore.
The mild temperate climate, calcareous or volcanic soils, make it an excellent area for growing asparagus. The risotto with asparagus tips is very good, flavoured with extra virgin olive oil Canino DOP, another fine local product.
The main events include the Festa di San Rocco on August 16th and the historical re-enactments of the Holy Week (Settimana Santa).
