Sonargaon is the ancient capital of both Hindu and Muslim rulers. Remnants of those 13th- and 14th-century reigns are scattered throughout the area, though there are virtually no reminders in modern Sonargaon itself. Mograpara, just a few kilometers from Sonargaon, has the best collection of ancient buildings, including several important tombs. Just outside Mograpara is the 16th-century Goaldi Mosque (a folk-art museum) and Painam Nagar (a century-old ghost town, complete with decaying mansions and a Hindu temple). Sonargaon is an easy day trip from Dhaka, but you could also stop there on your way to Chittagong. 18 mi/25 km southeast of Dhaka.
