It is popularly known as Masjid Acheh. It was founded in 1808 (after Masjid Kapitan Keling was built). The philanthropist was Tengku Syed Hussain Idid, who donated his land (wakaf). His grave is at the rear/kiblat side of the masjid. The compound houses Masjid Acheh, 2 big old wooden houses (one is not used), an old kampung house on stilts with ceramic roof tiles & walls painted black. There are a few blocks of modern townhouses which border the front entrance of the grounds. There are two major entrances to the grounds, one on Lebuh Acheh directly faces the minaret, and the other is nearer the ablution venue. There are passages/alleys in between the blocks of townhouses.
