This wall extends from the castle and has stone carvings of various animals which would have been very exotic when it was created. Much fun 🙂

A huge garden with flowerbeds as far as the eye can see. The roses are currently in season and the variety and quality is outstanding. Thank you to all those who maintain this flower Paradise ❤️

The footbridge over the Taff here was built in the 1980s by Cardiff University in tandem with development of nearby student accommodation. Engineering students were involved in the bridge project.
