Connected with the walls of the ancient castle, and upon a somewhat higher level than the keep, there stands the high round church of the Templars, with buttresses of immense strength reaching to the parapet, and a crumbling square bell tower upon one of its faces. Upon an ancient slab let into the sides of the church an inscription tells how Dom Affonso, first King of Portugal, and Gualdrim Paes, master of the Portuguese Templars, constructed this edifice in 1108. Joined to this ancient structure is one of the most astounding specimens of Manueline architecture in Portugal, built in the early sixteenth century, when all the country was pulsating with new life and eager longings. It is the choir and chapter-house, and behind them is the ruin of the great monastery of the Order of Christ. Words are weak to convey an idea of the capricious splendour of the choir and chapter-house so far as they remain undefaced, for later ages have done their best to spoil the edifice. Eight cloisters have been built around it, and tacked on to it, by the sixteenth and seventeenth centuries. Its lovely Manueline doorway has been marred, and the east end of the building blocked as high as its upper windows by the “Cloister of the Philips.” [Illustration: THE CHOIR AND CHAPTER-HOUSE, THOMAR.] But notwithstanding all the vandalism, enough of the Manueline building remains intact to strike the beholder with reverent wonder at the intricate beauty of the work, and the inexhaustible invention of the design. The doorway stands in a recess reaching to the parapet, and enclosed within an arch of surprising beauty, of which the under curve is lined with an elaborate pendent ornament. Within the recess filling the whole space and over the door itself, figures in niches stand under canopies and upon pillars in which caprice and intricacy surpass themselves. Coiled cables, bossed spirals, floreated pinnacles, armillary spheres, crosses, and intertwined branches, stand out in high relief and under cut, as if the sculptors had purposely sought difficulties in order to overcome them. The arch of the door itself is beyond description, so luxuriant is the design of the chiselled stone which forms the three grooves and two spiral pilasters around it. The parapet of the whole edifice is similarly rich, alternating the cross of the Order with the armillary sphere; and although most of the lower part of the walls is hidden, the view of the east end with its two corner towers, as seen from the roof of the adjoining cloister, is magnificent. The lower window, which lights the interior of the choir, is a massive tangle of outstanding cables; each point being crowned by the cross and the armillary sphere which formed the device of the grand master, the famous Prince Henry the Navigator. Around one of the corner towers a great chain cable, each link carved entire in stone, is braced, and around the other an equally tremendous buckled belt, representing the
