This Roman archaeological museum tells the story of Roman Heerlen and Roman South Limburg. The varied collection consists of Roman objects from and around Coriovallum: the Roman city that lies below Heerlen.

Masterpiece is the Roman bathhouse: the best preserved Roman (public) bathhouse in the Netherlands. This bathhouse with 500 meters of Roman wall work and some 2500 m2 of floor space has been very well preserved. You are most welcome to come and take a look and dive into our history.

Discovery of the bathhouse

The public bathhouse on the current Coriovallumstraat was discovered just before the Second World War. A grand discovery that underlined how large and prosperous Coriovallum had been in Roman times. The bathhouse was dug up during the war and provisionally covered with straw and silver sand. Only thirty years later, the current museum about the bathhouse was built to make the site available to the public. In 1977, the Thermenmuseum opened its doors and the first visitors came in to take a look.

The bathhouse way back then

Water equals health!
Taking a bath was very important in Roman culture. Sanitas per aqua (health through water) as they used to say. In modern terms, a Roman public bathhouse was a combination of wellness, gym, and health center. A visit to the bathhouse was a social event for which you reserved enough time. Here you met other people, you did sports, you got a massage, you could go for a beauty treatment or a visit to a doctor.

Wealthy Romans had the luxury of having their own bathroom at home. The more common man went to a bath house (balnea) or a bath complex (thermae) every day. The Thermenmuseum was a public bathhouse.

You were allowed to enter against payment of a modest amount. Men and women bathed separately: women were welcome in the morning, men the rest of the day until sunset. You put your clothes away in special niches and then went nude bathing and exercising.

You could choose from different rooms:

  • caldarium or the warm room: here you could take a hot water bath.
  • epidarium or the lukewarm room: here you could get rubbed in with bathing oil.
  • sudatorium or the sweat room: the warm air opened up your skin pores. The bath oil was scraped off the skin together with the dirt with a bath scraper.
  • frigidarium or the cold room: here you could plunge into one of the two dipping pools.

Temperature

A bathhouse obviously had to stay at the right temperature. Therefore, there was a continuous fire in the praefurnium. The hot air heated up the rooms through the space underneath the floors and between the walls. The water in the hot water bath was heated via the hot air underneath and via a boiler that stood on the heating channel. From here the hot water was fed directly into the bath.

Meeting place

The bathhouse was primarily a meeting place where the locals met. But you could also make new contacts with people who were passing through. In between, you ate snacks. We know this through discoveries of tableware, oyster scoops and even oyster shells in the Thermenmuseum. All this made the bathhouse in the center of Coriovallum town one of the most important places for residents of the city and region to go to.
