Marked by three gold-topped white spires (called shikars) in the style of a traditional Hindu temple, each marking an altar inside the building, the Shri Swaminarayan Mandir temple was the first Swaminarayan temple in Wales. Opened in 1982, it acquired its distinctive appearance following major refurbishment work between 2005 and 2007.

Dinorwig pumped-storage hydro-electric power station is one of the largest engineering projects in Britain. Work began on the conversion of the quarry in 1975, when millions of tons of slate had to be removed to create tunnels and machine halls. Dinorwig comprises sixteen kilometres of underground tunnels, deep below Elidir mountain. Its construction required 1 million tonnes of concrete, 200,000 tonnes of cement and 4,500 tonnes of steel.
Externally, all that is visible is a door on the side of the mountain, ensuring that the area of outstanding natural beauty is not impaired. The visitor centre closed in 2018. Read more in our site record: https://coflein.gov.uk/en/site/408885

The bell-frame, dating to 1537-8, is a King-post design to hold a peal of 3 bells. A system of Arabic numbers are carved into the timbers which would have helped guide those tasked with assembling (or reassembling) the frame up in the tower.
The church is a Grade II* Listed Building, an example of a largely unaltered Welsh medieval church. It is plain and dignified in style and built in a cross shape, complete with imposing 3-storey central tower. It is the best example of the three surviving cruciform churches with central towers in Ceredigion.

Carmel United Reformed (Independent) chapel, built c.1829, is in the later Vernacular style of the long-wall entry type and is distinguished by an unspoilt interior retaining its early 19th century character. There are just four rows of wooden benches facing a simple pulpit.
