The church then, though interesting from its plan, is--inside especially--remarkably unpleasing, though it is perhaps only fair to attribute a considerable part of this disagreeable effect to the state of decay into which it has fallen--a state which has only advanced far enough to be squalid and dirty without being in the least picturesque. Far more pleasing than the church is the round cloister behind. In it the thirty-six Ionic columns are much better proportioned, and the capitals better carved; on the cornice stands an attic, rendered necessary by the barrel vault, heavy indeed, but not too heavy for the columns below. This attic is panelled, and on it stand obelisk-bearing pedestals, one above each column, and between them pediments of strapwork. (Fig. 98.) Had this cloister been square it would have been in no way very remarkable, but its round shape as well as the fig-trees that now grow in the garth, and the many plants which sprout from joints in the cornice, make it one of the most picturesque buildings in the country. The rest of the monastic buildings have been in ruins since the siege of 1832. [Sidenote: Coimbra, Santa Cruz Sacristy.] The sacristy of Santa Cruz at Coimbra must have been begun before Nossa Senhora da Serra had been finished. Though so much later--for it is dated 1622--the architect of this sacristy has followed much more closely the good Italian forms introduced by Terzi. Like that of the Sé Velha, the sacristy of Santa Cruz is a rectangular building, and measures about 52 feet long by 26 wide; each of the longer sides is divided into three bays by Doric pilasters which have good capitals, but are themselves cut up into many small panels. The cornice is partly carried on corbels as in the Serra church, but here the effect is much better. There are large semicircular windows, divided into three lights at each end, and [Illustration: FIG. 98. OPORTO. CLOISTER, NOSSA SENHORA DA SERRA DO PILAR.] [Illustration: FIG. 99. COIMBRA. SACRISTY OF STA. CRUZ.] the barrel vault is covered with deep eight-sided coffers. One curious feature is the way the pilasters in the north-east corner are carried on corbels, so as to leave room for two doors, one of which leads into the chapter-house behind the chancel. (Fig. 99.) [Sidenote: Lisbon, Santa Engracia.] Twenty years later was begun the church of Santa Engracia in Lisbon. It was planned on a great scale; a vast dome in the centre surrounded by four equal apses, and by four square towers. It has never been finished, and now only rises to the level of the main cornice; but had the dome been built it would undoubtedly have been one of the very finest of the renaissance buildings in the country.
