Located on the edge of Marshfield in the beautiful countryside between Cardiff and Newport, Y Maerun offers the perfect venue for a catch up with friends, a relaxing meal with family or simply a refreshing drink with colleagues after work. It is not certain, but old maps show a building on the present site known as Glandwr Inn, pre 1850. We know the railway line nearby completed the Gloucester to Swansea route in June 1850, and it's probable that the inn was then renamed the Railway Hotel to take advantage of the adjacent Marshfield station.

The bridge was erected as part of a carriage drive between Ruperra Castle and Machen church, probably coinciding with the appointment of Augustus Morgan, son of Sir Charles Morgan, to the living of Machen circa 1828

This paved shared-use trail alongside the River River Rhymney is a really delightful way to avoid the busy Newport Road on the other side of the industrial estate, and you get to soak up some nature too. The trail features on National Cycle Route 4 and the Celtic Trail, but be sure to take care here as it is also popular with walkers and runners from nearby Bedwas and Trethomas.
