The River Gwili gives its name to a number of settlements, as well as the Glangwili General Hospital. The Carmarthen Aberystwyth Line once followed the course of the river between Abergwili and Llanpumsaint and the dismantled railway line can still be seen right along the valley. In 1978 a section of the line was reopened in Bronwydd as a heritage railway and was given the name Gwili Railway.[1]
