The cemetery contains the graves of Lord Tonypandy, Tommy Farr, Lewis Jones and James Kitchener Davies.

[5] Trealaw is served by two railway stations on the Transport for Wales train services from Cardiff: Dinas and Tonypandy.

At the lower end, there was Davies's soft drinks factory in Marjorie Street, while in Trealaw Road the Co-op and the Hopkin Morgan bakeries provided the main employment.

For recreation, the main venue is Maes-yr-Haf Education Centre, founded by the Society of Friends (Quakers) in the 1920s where everything from pottery to drama was taught.

Today, there is a more limited range of activities, while the Dan Murphy Day Centre (named after a former councillor) on the site provides meals and a meeting place for the area's senior citizens.

The Bute closed in 1964 and was subsequently demolished to provide a car parking area for the Trealaw Workingmen's Club next door which has now acquired the 'Res' soubriquet.

In the 19th and early-20th century, behind Dinas Arms was the Brithweunydd Hotel, a low-class lodging house for workers attracted to the area by the burgeoning coal mining industry.
