Tonypandy is also the site of one of the only two permanent Middle Ages fortifications found within the Rhondda Valley. Named Ynysygrug, it was a lesser motte and bailey earthwork defence. The fortification appears to have consisted of a wooden tower surrounded by a small fortified courtyard. Placed around the 12th or early 13th century, the remains of the fortification were mostly destroyed when the town's railway was constructed in the 1800s. Over the past two hundred years, the fortification had been wrongly thought to be the burial place of Rhys ap Tewdwr or a druidic worship site.
The regional library service recounts that the name 'Tonypandy' means the meadow of the fulling mill which was established there in 1838. "E. D. Lewis in his work The Rhondda Valleys provides us with an outline history of the mill that once stood in Tonypandy, and from which the town took its name".
It is one of the principal shopping areas in the Rhondda and has many shops to cater for all needs. A 30,000 sq ft Asda has recently opened on the site of the old Scotch Colliery, creating 300 jobs.
The town is served by Tonypandy railway station.
Tonypandy has a King George's Field, the Athletics Ground, in memorial to King George V
