Some of the most emblematic buildings of the city were built during this period, including the Serranos Towers (1392), the Lonja (1482), the Miguelete and the Chapel of the Kings of the Convent of Santo Domingo. In painting and sculpture, Flemish and Italian trends had an influence on artists such as Lluis Dalmau, Peris Goncal and Damia Forment. Literature flourished with the patronage of the court of Alfonso the Magnanimous, supporting authors like Ausias March, Roic de Corella, and Isabel de Villena.
