How did barrackpore Trinidad get its name?

There is no town called Barrackpore, Trinidad. However, if you meant Barrackpore in Trinidad and Tobago (located in Penal-Debe region), its name is derived from its former use as a British military outpost during the colonial era. 'Barrack' refers to military lodgings, and 'pore' means 'place' in Bengali. So, barrackpore means "location of the barracks".
