The Central Mineral Baths (Централна минерална баня, Tsentralna mineralna banya) is a landmark in the city center of Sofia, the capital of Bulgaria, a city known for the mineral springs in the area. It was built in the early 20th century near the former Turkish bath (then destroyed) and was used as the city's public baths until 1986.

Thermopylae (/θərˈmɒpɪliː/; Ancient Greek and Katharevousa: Θερμοπύλαι, romanized: Thermopylai; Ancient: [tʰermopýlai], Katharevousa: [θermoˈpile̞]; Demotic Greek (Greek): Θερμοπύλες, romanized: Thermopyles [θermoˈpiles]; "hot gates") is a narrow pass and modern town in Lamia, Phthiotis, Greece. It derives its name from its hot sulphur springs. In Greek mythology the Hot Gates is one of the entrances to Hades.

Thermopylae is the site of the Battle of Thermopylae between the Greek forces (including Spartans, Thebans and Thespians) and the invading Persian forces, commemorated by Simonides of Ceos in the epitaph, "Go tell the Spartans, stranger passing by, That here we lie, having answered our common oaths." Thermopylae is the only land route large enough to bear any significant traffic between Lokris and Thessaly. To go from north to south along the east coast of the Balkans requires use of the pass.In ancient times it was called Malis, named after the Malians (Ancient Greek: Μαλιεῖς), a Greek tribe that lived near present-day Lamia at the delta of the river Spercheios in Greece. The Malian Gulf is also named after them. In the western valley of the Spercheios their land was adjacent to the Aenianes. Their main town was named Trachis. In the town of Anthela, the Malians had an important Temple of Demeter Amphictyonis, an early center of the Anthelan Amphictyony.

Addis Ababa (/ˌædɪs ˈæbəbə/ AD-iss AB-ə-bə; Amharic: አዲስ አበባ [adˈdis ˈaβəβa] , lit. 'new flower'; Oromo: Finfinnee, lit. 'fountain of hot mineral water') is the capital city of Ethiopia, as well as the regional state of Oromia. With an estimated population of 2,739,551 inhabitants as of the 2007 census, it is the largest city in the country and the eleventh-largest in Africa. At an elevation of 2,355 metres (7,726 ft), it is the fourth highest capital city in the world and the highest capital in Africa. Addis Ababa is a highly developed and important cultural, artistic, financial and administrative center of Ethiopia.

The founding history of Addis Ababa dates back to the late 19th century by Menelik II, Negus of Shewa, in 1886 after finding Mount Entoto unpleasant two years prior. At the time, the city was a resort town; its large mineral spring abundance attracted nobilities of the empire and led them to establish permanent settlement. It also attracted many members of the working classes – including artisans and merchants – and foreign visitors. Menelik II then formed his imperial palace in 1887. Addis Ababa became the empire's capital in 1889, and subsequently international embassies were opened. Urban development began with the 20th century, without any prior planning.

Mineral water is water from a mineral spring that contains various minerals, such as salts and sulfur compounds. It is usually still, but may be sparkling (carbonated/effervescent).

Traditionally, mineral waters were used or consumed at their spring sources, often referred to as "taking the waters" or "taking the cure", at places such as spas, baths and wells.

A spa town is a resort town based on a mineral spa (a developed mineral spring). Patrons may visit spas to "take the waters" for their purported health benefits.

Thomas Guidott set up a medical practice in the English town of Bath in 1668. He became interested in the curative properties of the hot mineral waters there and in 1676 wrote A discourse of Bathe, and the hot waters there. Also, Some Enquiries into the Nature of the water. This brought the purported health-giving properties of the waters to the attention of the aristocracy, who started to partake in them soon after.

Travertine (/ˈtrævərtiːn/ TRAV-ər-teen) is a form of fresh water limestone deposited around mineral springs, especially hot springs. It often has a fibrous or concentric appearance and exists in white, tan, cream-colored, and rusty varieties. It is formed by a process of rapid precipitation of calcium carbonate, often at the mouth of a hot spring or in a limestone cave. In the latter, it can form stalactites, stalagmites, and other speleothems.

Travertine is frequently used in Italy and elsewhere as a building material. Similar, but softer and extremely porous deposits formed from ambient-temperature water are known as tufa.

Vichy (/ˈvɪʃi, ˈviːʃi/, French: [viʃi]; Occitan: Vichèi [viˈtʃɛj]) is a city in the central French department of Allier. Located on the Allier river, it is a major spa and resort town and during World War II was the capital of Vichy France. As of 2022, Vichy has a population of 25,702.

Known for its mineral springs since the Roman times, Vichy had become a major destination for the French nobility and the wealthy by the late 18th century. The town developed further under the patronage of Napoleon III. Following the 1940 armistice, the pro-German collaborationist government headed by Philippe Pétain was set up at Vichy, which remained the de facto capital of the French rump state for the next four years. After the war, the city experienced a period of great prosperity but went into decline from the 1960s.

Spa (French pronunciation: [spa] ; Walloon: Spå) is a municipality and city of Wallonia in the province of Liège, Belgium, whose name became an eponym for mineral baths with supposed curative properties. It is in a valley in the Ardennes mountains 35 km (22 mi) south-east of Liège and 45 km (28 mi) south-west of Aachen. In 2006, Spa had a population of 10,543 and an area of 39.85 km (15.39 sq mi), giving a population density of 265/km (690/sq mi).

Spa is one of Belgium's most popular tourist destinations, being renowned for its natural mineral springs, and production of "Spa" mineral water, which is exported worldwide. The motor-racing Circuit de Spa-Francorchamps, just south of the nearby village of Francorchamps, also hosts the annual Formula One Belgian Grand Prix and various endurance races such as the 24 Hours of Spa. The world's first beauty pageant, the Concours de Beauté, was held in Spa on 19 September 1888. The town also hosted the Tour de France on 5 July 2010, when stage 2 of the race ended there.
