Porthkerry Viaduct is a notable railway viaduct located near Porthkerry Park in the Vale of Glamorgan, Wales. It was built in the mid-19th century (completed in 1887) to carry the Barry Railway over the Porthkerry Valley. The structure features a series of elegant arches and is constructed from local sandstone, making it both a functional piece of infrastructure and a striking landmark in the area. The viaduct is approximately 1,200 feet long and stands about 100 feet high at its tallest point, with 13 arches. It is an excellent example of Victorian engineering and is often appreciated for its aesthetic appeal as well as its historical significance. The surrounding area is popular with walkers and nature enthusiasts, thanks to the scenic views and nearby parkland. Today, while the Barry Railway is no longer in operation, the Porthkerry Viaduct remains an important heritage site and is a popular spot for photography and sightseeing.

Located near the village of Rhoose in the stunning Vale of Glamorgan, Rhoose Point (Welsh: Trwyn y Rhws) stands as a captivating headland and settlement. Nestled in the southernmost reaches of Wales, this picturesque locale holds the distinction of being the most southerly settlement in the country. While some argue that nearby Breaksea Point also lays claim to this title, Rhoose Point remains a remarkable destination that showcases the natural beauty and coastal charm of mainland Wales.
