According to the Bengali Vocabulary, the name Paharpur (Pahar = hill, pur = locality) means a locality of hill. It is a village in Badalgachi Upazila of Naogaon District. The nearest railway station of Jamalganj that lies on the Khulna-Parvatipur rail tract and is connected with Paharpur by a 5km long brick metalled bye-way. Paharpur can also be reached from its nearest airport, Sayedpur, following a metalled road via Joypurhat. The village contains the ruins of a Buddhist monastery which was called Somapura Mahavihara (the great monastery situated in the locality of moon) in the ancient Buddhist World. It is now a World Cultural Heritage (BGD. 292)

The monastery is square in plan, being 281m on each side. Built by Dharmapala (781-821 AD) the second ruler of the Pala dynasty, and reconstructed at least twice by his descendants, each of its with has thick exterior wall with two entrance provisions on the north and one in the east. Besides, there has a row of monastic cells, fronted by a running corridor, abutting the exterior wall. Some of the cells contain solid pedestals. There has also a sub-worshipping point in the mid-most part of each wing excepting the north one. Each worshipping point, excepting the southern one, has a staircase connection with the monastery courtyard in front. In the center of the open courtyard of the monastery there stands the residual vestige of a four-faced shrine.

The central shrine is a terraced structure springing from a cruciform ground plan and expanding from a mid-pile of square configuration. The upper terrace has in its each side a sanctum fronted by an ante-chamber with circumambulatory passage around. Each of the second and first terraces has nothing but a circumambulatory passage. The passages of the lower terrace, however, are now covered under recently accumulated soil. Its wall has 63 inches at plinth level, each being provided with a stone sculpture. Whereas the un-plastered wall surfaces of the lower two terraces are decorated with friezes containing terracotta plaques showing different scenes. The cornices of all terraces are turgent and lavishly relieved with carved bricks showing chain, petal, pyramidal, dental, net and lozenge motifs. Moreover, at the juncture of the cornices there are stone gargoyles ended in grinning lion faces.

The courtyard around the central shrine is dotted with several units of straggling structural ruins. Of them, Panchavede > a group of five votive stupas>near the south-eastern comer, a kitchen towards west of Panchavedi, a long paved dinning arrangement towards north-west of Panchavedi and a model of the central shrine on the north of Panchavedi are a few to note. The northeast comer is also occupied by another group of structures, They appear to have been related to office establishments. Close to the basement of the central shrine a number of wells, votive stupas, vedika cruciform model etc. are noticed. The western half of the courtyard is relatively barren in structural finding.

A good number of objects cultural have been salvaged from Paharpur, They include sculptural pieces, terracotta plaques, pottery, domestic tools, ornaments, coins, seals, ceilings, votive stupas etc. They are now housed in Asutosh Museum Kolkata, Bangladesh National Museum , Varendra Museum, Paharpur Museum and other site museums in Bangladesh.

Of these antiquities sculptural pieces as well as sculptured plaques are artistically most alluring. Most of the sculptural pieces are medium in size and a few are smaller. All of them are wrought on stone save a few of metal. Stucco sculptural pieces are, however, not altogether lacking. Among the metal sculptures, the fragmentary bust of a Buddha is worth noted because of its artistic excellence. Only one stone sculpture is related to Mahayana order, the remaining being Hindu. In dating parlance, they may be placed in the 7th-12th AD time-bracket.

The next group of alluring art objects is represented by terracotta plaques. They are at least 2800 in number and appear to be contemporaneous to the 1st constructional period of the Pala monastery. Their sizes vary between 40cm x 30cm x 6cm and 18cm square. They depict diverse scenes reflecting the then socio-political, economic and martial aspects.

The mosque is located on the western embankment of the Thakur Dighi and to the southwest of the mausoleum of Khan Jahan. The square mosque (15.1 meter) is roofed over with nine hemispherical domes rest on four free- standing stone columns.

It has three pointed arched openings on the north, south and east sides bordered within tall rectangular frames. Above the arches there are horizontal rows of moldings.

The western wall is relieved with three semicircular mihrabs of which the central one is larger and is projected to the west. The multi-cusped mihrabs are decorated with terracotta floral, scroll and foliage patterns within rectangular panels. Center of each mihrab is decorated with chain and bell motif. Apexes of the arches have diaper designs and large rosettes at the spandrels. Rest three walls are relieved with only two niches in each.

The corner turrets are round and are faceted by eight bands of moldings. The exterior walls are relieved with vertical panels. The curved cornice is very prominent.

The second important monument of Khalifatabad is the single domed mausoleum of Khan Jahan (Pl.23) located on the northern embankment of a large tank locally known as Thakur dighi. It is about 2km east-southeast of Sixty Dome Mosque.

The tomb is a square building measuring 13.70 meter each side. At the base of the brick wall 5 courses of black Stones have been used. There is an arched entrance in the middle of each side of which the northern one is now closed. The corner towers are faceted at regular intervals with seven brick moldings and crowned with ribbed cupolas. The walls are 2.5 meter thick. Each wall is relieved with two multi cusped arched niches.

The tomb accommodates a stone built sarcophagus in the middle of the floor and actual, grave underneath. The floor was richly embellished with colored glazed tiles which are now missing.

The sarcophagus is profusely engraved with the verses from the holy Quran, Persian expressions and date (27 Zilhaz, 863 AH [24-25 October 1459 AD]) of the demise of the saint Khan-ul-Azam Ulugh Khan-i-Jahan by title. The walls of the crypt, which is now closed, are also full with inscriptions. An attempt to decipher those inscriptions may help to get the Khan Jahan’s identity and also to reconstruct the history of the region.

On the close west of this tomb there is another stone sarcophagus known as Peer Alt Taheerer Majar who was close associate of Khan Jahan. Further west there is an identical but smaller single domed mosque.

The tomb is enclosed by an inner and outer compound. The inner boundary wall accommodates three gateways, one in each side except north. The main gateway in the west is now closed. The outer enclosure has six entrances in it.

The most spectacular and magnificent monument of Khalifatabad, stands on the eastern bank of a large water tank, locally known as Ghora dighi. It is about 7km west of Bagerhat town. Khulna-Bagerhat high way passes to the south of the mosque. This most imposing brick-built mosque is commonly known by its highly misleading name of Shat Gambuj Masjid or Sixty Dome Mosque. Actually this is roofed over with 77 squat domes including 7 chauchala or four segmented hut shaped domes in the central row.

It is the largest mosque of medieval Bangladesh with its external dimension 49 meter long and 33 meter wide. The large prayer chamber is provided with 11 arched doorways on the east and 7 each on the north and south. The interior of the mosque is divided into 7 longitudinal aisles and 11 deep bays by 60 stones columns of which five are brick piers. Rows of endless diminishing arches spring from these pillars. These arches support the domes. Recent restoration works have covered those stone columns excepting one.

There are ten concave mihrabs on the western wall of which the central one is of stone while the flanking 9 mihrabs are decorated with terracotta motifs. There is a small arched doorway in the western wall close to the central mihrab. The corner turrets are raised above the slightly curved parapet capped by rounded cupolas. The eastern turrets are tall and have entrances from the anterior of the mosque through staircases while the western turrets are dwarfish without staircases. The facade is relieved with usual curved cornice. Besides, over the central arched doorway there existed a small triangular pediment. After repair this pediment is not seen.
