The name Les Escaldes comes from the presence of numerous hot springs, which produce highly sulphurous and nitrogenous waters at temperatures between 22 and 66 °C (72 and 151 °F).

[1] There was a textile industry from the Middle Ages, producing woven fabrics and umbrellas in several guilds.

[1] In the 1800s some proposed establishing baths to take advantage of the natural hot springs, but there was resistance from the government of Les Escaldes, possibly for fear that visitors to the hot springs would bring diseases to Andorra.

[2] Nowadays Les Escaldes is home to the spa resort Caldea.

The Spanish international primary school Escuela Española de Escaldes serves the community.
