The most notable monuments of the Moguls are the +Mosque of Akbar+ (1556-1605) at Futtehpore Sikhri, the tomb of that sultan at Secundra, and his palace at Allahabad; the +Pearl Mosque+ at Agra and the +Jumma Musjid+ at Delhi, one of the largest and noblest of Indian mosques, both built by Shah Jehan about 1650; his immense but now ruined palace in the same city; and finally the unrivalled mausoleum, the +Taj Mahal+ at Agra, built during his lifetime as a festal hall, to serve as his tomb after death (Fig. 86). This last is the pearl of Indian architecture, though it is said to have been designed by a European architect, French or Italian. It is a white marble structure 185 feet square, centred in a court 313 feet square, forming a platform 18 feet high. The corners of this court are marked by elegant minarets, and the whole is dominated by the exquisite white marble dome, 58 feet in diameter, 80 feet high, internally rising over four domical corner chapels, and covered externally by a lofty marble bulb-dome on a high drum. The rich materials, beautiful execution, and exquisite inlaying of this mausoleum are worthy of its majestic design. On the whole, in the architecture of the Moguls in Bijapur, Agra, and Delhi, Mohammedan architecture reaches its highest expression in the totality and balance of its qualities of construction, composition, detail, ornament, and settings. The later monuments show the decline of the style, and though often rich and imposing, are lacking in refinement and originality. [Illustration: FIG. 86.--TAJ MAHAL, AGRA.]
