Llanwrtyd Wells grew in the 19th century as a spa town around the Ffynnon Ddrewllyd, 1.5 miles from the much older settlement of Llanwrtyd. The town was also known as an eisteddfod site, and is the site of both the WorldBog Snorkelling Championships and the annual Man versus Horse Marathon, as well as other annual events. The Abernant Lake Hotel was built on the site of an old farm, to cater for the many visitors, keen to take the spa waters. The hotel grounds include a lake created in 1903 by damming an oxbow of the Irfon. During World War II, the hotel was home to Bromsgrove School, evacuated from Worcestershire, and from 1943-45 to the CzechoslovakState School for Refugee Children. It remained as a hotel until 2007 when it became home to a multi-activity centre for school groups and families. Llanwrtyd Wells had two golf clubs and courses during the 20th century, both now defunct. The early course was at the Dol-y-coed Hotel and the later one at Abernant Lake Hotel.
Cambrian Mill
Built in 1852, the Cambrian Woollen Mill was the largest woolen mill in the Llanidloes area, employing over 250 workers at its peak. It was reduced to an empty shell by a fire in November 1889, but rebuilt in 1902 and has been in continuous operation since then. It is one of very few woolen mills still operating in Wales. According to the mill's website, visitors can experience "700 years of weaving history".
Spa
Following the discovery in 1732 by the Rev. Theophilus Evans of waters claimed to have healing properties, Llanwrtyd Wells became a spa town. The spa was referred to as Ffynnon Ddrewllyd "Stinking Well" because of the strong smell of hydrogen sulfide. The spa is located at the site of the Dol-y-Coed Hotel, now the home of Charcroft Electronics. The fashion for spas reached its peak in the Victorian era and many of the hotels in the town date back to that time. The Belle Vue Hotel, the only purpose-built hotel in Llanwrtyd, was built in 1843.
Modern times
In contrast to its past history as a spa town, when hundreds flocked to take the waters for their claimed medicinal effects, the area is now better known for recreations such as pony trekking, mountain biking, walking and birdwatching, and for its annual Man versus Horse Marathon, Beer Festival and World Bog Snorkeling Championship. The town's largest employer Charcroft Electronics is located in buildings which were previously the Dol-y-Coed Hotel. The hotel, on the banks of the Irfon, dates from about 1535.
Governance
A Llanwrtyd Wells electoral ward exists, which also includes the neighbouring communities of Llangamarch and Treflys. This ward had a population of 1,875 at the 2011 Census. Unlike many small towns in rural Wales, Llanwrtyd station still has a passenger train service. Heart of Wales line trains between Swansea and Shrewsbury call four times a day each way Monday to Saturday and twice each way on Sunday.
Famous residents
The town is the home of Robin Kevan, also known as "Rob the Rubbish", who has become famous for his efforts to clean up Britain's countryside.
