Along Jalan Gambier you will see a passageway that leads to the next road, Jalan India. Halfway through, you will encounter an Indian Muslim mosque, hidden away in the middle of the city. The Mosque's structure has undergone many changes since it was originally built by Kuching's Indian Muslim community in the mid 19th century. Jalan Gambier is named after a type of shrub, gambir which was Sarawak's main export in 1894. The plant's leaves produce an extract that is used to dye and tan leather.
