## Key facts

- **Traditional material:** Ardennes slate
- **Slate output, late 19th century:** About 6 million slates a year (Haut-Martelange)
- **Workforce about 1900:** About 600
- **Last slate mine closed:** 1986
- **UNESCO site:** City of Luxembourg (1994)

Luxembourg is a small, landlocked country divided between the wooded Ardennes uplands (the Oesling) in the north and the lower Gutland to the south. Its traditional roofs are closely tied to the Ardennes slate belt, which runs across the border from Belgium, and for about two centuries the slate mines of Haut-Martelange were among the most important in Europe.

## Climate and hazards

Luxembourg has a temperate climate with rain spread through the year and colder, snowier winters on the Ardennes plateau.

## Roofing history

Roman villas at Echternach (from about AD 70), Mamer and Goeblange show that substantial masonry building began in the Roman period. Medieval castles such as Vianden, Bourscheid, Beaufort and Clervaux, and Romanesque and Gothic churches at Echternach, Diekirch and elsewhere, are the oldest surviving roofed buildings, though most have been re-roofed many times.

Underground slate mining began at Haut-Martelange, on the Belgian border, by the 18th century; one account dates the first mines to the end of the 17th century, while the site's museum dates them to the end of the 18th century. A railway link in 1890 allowed large-scale export, and the same year the Rother family of Frankfurt bought the mines and the village. By the end of the 19th century the works produced about 6 million roofing slates a year and around 1900 employed about 600 people. Pneumatic tools arrived from 1900 and a company power station was built around 1904. In the 19th century the mines were among Europe's main slate exporters and a significant part of Luxembourg's exports.

Sales stagnated from 1930 in the economic crisis, and after 1960 the industry declined because of new roofing materials and cheap imported slate. The last Luxembourg slate mine closed in 1986.

## Traditional and vernacular roofs

Natural slate is the characteristic roof of the Oesling and of historic buildings across the country.

## Roofing today

Slate now comes from abroad, as no domestic mines operate.

## Codes, standards and regulation

European EN standards apply to roofing products.

## Industry

The former Haut-Martelange slate works is now a museum. A friends' association formed in 1992 to reopen the mines to the public, the municipality of Rambrouch bought the village, industrial buildings and mines in 1993, and in 2018 the government invested EUR 7.1 million in a museum open daily, with underground visits to a depth of 42 m (138 ft). Since 2019 the Musée de l'Ardoise is run by an association of the state, the municipality and the friends' group.

## Notable roofs

- **City of Luxembourg** old quarters and fortifications, designated a UNESCO World Heritage Site in 1994.
- **Vianden Castle**, an 11th-13th century castle built on a Gallo-Roman fort.
- **Haut-Martelange**, the former slate village and mines.
