The Tetulia Jami Mosque (), also known as the Khan Bahadur Salamatullah Mosque, and the Tetulia Shahi Mosque, is located in village of Tetulia (or Tentulia) in Tala Upazila in the district of Satkhira in Bangladesh. The founder of the mosque was Khan Bahadur Maulvi Qazi Salamatullah Khan, of the zamindar (feudal-lord) Qazi family of Tetulia, who was also the founder of the mansion known as Salam Manzil (now in ruins) in the vicinity. The six-domed mosque was built Mughal style in 1858–59 and resembles those built by Tipu Sultan's descendants, as does the Salam Manzil, now in virtual decay. In 1982, the front of the decaying “Shingho Doroja” (“Main Door” in the Bengali language) – that is, the gateway and entrance to Salam Manzil – appeared to have inscriptions or patterns on the wall. Walking through the gate, one would find a spacious compound containing a lot of greenery. A very long verandah with a crumbling roof, supported by a twin-pillar system, overlooked the compound. Opening onto the verandah were dilapidated chambers, which used to function as offices in the past, when the mansion was in a working state. In the past, one or more end-rooms of the verandah had housed palkis (palanquins). One particular palki was enormous and twelve bearers were required to carry it. It is unusual to find the use of the twin-pillar system in a remote village of Bengal in the mid 19th century. The twin-pillar system was necessary to support the roof, which had several layers of reinforcement. The distance of the roof from the ground appeared to be at least ten and a half feet. In the present time, the "Shingho Doroja" has been renovated to a different style, though the rest of the Salam Manzil is in complete ruins. Salamatullah Khan dynasty Khan Bahadur Salamatullah Khan was preceded by his father Maulvi Qazi Sana’atullah, who was the son of Qazi Amanatullah. The latter's father was Qazi-ul-Quzat (Chief Justice) Baqaullah Khan (circa mid to late 18th century AD) – a Mughal sanad (title) holder. Khan Bahadur Salamatullah Khan was succeeded by his son Maulvi Qazi Hamidullah Khan. Hamidullah Khan married Azizunnessa Khatun, the Bengali poet. The latter's son Maulvi Qazi Mohammad Minnatullah Khan was a famous personality of the Qazi family of Tetulia. Minnatullah Khan had two sons, namely Khan Sahib Qazi Rizwanullah Khan and Qazi Mohammad Shafiullah Khan. By the time these
