In the same piazza are Palazzo Guarnieri and a Baroque staircase leading to the church of St. Roch (1576–1632), flanked by the so-called "Castle of Alboin" with the Torre dell'Orologio', once part of the Roman defensive apparatus. The Castle's attribution to the Lombard king of Alboin has no historical evidence The Pinacoteca, in Palazzo Villabruna, has works by Morto da Feltre, Cima da Conegliano, Gentile Bellini, Pietro Marescalchi and others. The church and the monastery of Santa Maria degli Angeli, begun in 1492, but entirely renovated in the 19th century, has maintained part of the ancient cloister.
