Lost Mosque

The Lost Mosque also known by its official name, Jame' As-Sahaba is an ancient mosque located in Panchagram, in Lalmonirhat District, in Rangpur Division of Bangladesh. A inscription discovered claims the mosque to be built in 69 AH (688/689 CE). The site often referred to as the 'Lost Mosque' or Harano Masjid, is of significant local interest, but its historical origins remain a subject of debate rather than scientific consensus. The site has not undergone a formal peer-reviewed archaeological excavation. Consequently, the claim that the mosque dates to 69 AH—based primarily on a terracotta inscription discovered by locals in 1986- lacks independent archaeological verification. Informal carbon dating inquiries, reportedly conducted on material from the site, have yielded inconclusive results. Some reports suggest that due to insufficient organic material and potential sample contamination, the dating remains unreliable; however, preliminary analysis indicated that the tested material may originate from the early 18th century, contradicting the earlier local claims of 7th-century origins.
