a small town of Zaragoza, in the fertile basin of the Jiloca. It contains a fine old Gothic church. From its position it is very liable to inundations, but the waters are carried off by a magnificent tunnel 2340 feet long, and 24 feet square, constructed in 1560, by a French architect named Pierre Bedel. For the first time since the construction of this great work the town was inundated in 1854, and a large portion of it swept away. Pop. 500.
