Venne realizzata intorno alla metà del XV secolo dalla famiglia della Rovere che aveva il vicariato di Caprarola in quel periodo.
Verso la fine dello stesso secolo l’acquedotto, che raccoglie le acque di alcune sorgenti dei monti Cimini, venne ampliato dalla famiglia Riario, come testimoniato dal loro stemma nella parte
superiore della fontana.
Quello sottostante invece, ove è raffigurato un albero di rovere con due capre salienti, è l’antico stemma comunale di Caprarola.
Fontanaccia or the Fountain of Faces
(not available in Chinese) The arched fountain, surmounted by a balcony, is known as “Fontanaccia” (the ugly fountain), a term which has been in use since 1588. Since 1850 it has also been known as “fountain of the boccacce” (fountain of the ugly faces). It was built during the construction of Via Diritti at the request of Cardinal Alessandro Farnese. The balcony is decorated with three coats of arms: the middle one belonging to the Cardinal himself; to its right the arms of the Duchy of Parma and Piacenza, Castro and Ronciglione; and to its left the arms of Duke Alessandro Farnese, the Cardinal’s nephew. You may notice a contrast between the part below the cornice, which was made of rose granite between 1562 and 1565, and the part with the coat of arms, made of gray granite. This might be because the arms were added later. Inside the arch, contained in three niches, are three masks that feed the basin. We know that in 1597, for the visit to Caprarola by Pope Clement VIII, the fountain was altered to provide wine instead of water.
面具喷泉
面具喷泉全部由白榴凝灰岩制成，1563年建成，1853年建成现在的模样。拱形结构，有一个单盆。拱形中央有一个假面饰，两边有较小的假面饰，在两个象征富裕的丰饶角之间是卡布拉罗拉的标志。在很长一段时间里，这个喷泉也被称为“泉水”。
