Green hills and farmhouses north of town surround this meticulously kept castle with a red roof. It was built in 1237, destroyed half a century later, and then rebuilt soon thereafter. There's a beautifully preserved cycle of medieval frescoes inside. A tavern in the courtyard serves excellent local food and wines. To get here from Piazza Walther, take the free shuttle (Tuesday–Sunday every half hour 10–5), or the number 12 or 14 buses. It's a 20-minute walk from Piazza
delle Erbe: head north along Via Francescani, continue through Piazza Madonna, connecting to Via Castel Roncolo.
