The replica of the old ‘Kundel’ washhouse, which stood at the entrance to the ruelle de la Tour, the only washhouse inside the town wall, was built in 2009 on the initiative of the Syndicat d'Initiative in a barn belonging to the local authority. In a small gallery on the first floor, you can find information about the finds made during the excavations carried out from 2003 onwards in the Baxeras dykes.

In 2013, the town of Grevenmacher created the ‘Turgaass’ open-air gallery in the ‘Turgaass’, which bordered the town wall and is located next to the replica of the ‘Kundel’. Here, visitors can learn interesting facts about Grevenmacher's historic past on six large, illustrated panels. The fortress wall was a square measuring 280 by 250 metres. There were 27 or 28 towers and four gates in the wall. The fortress tower still stands in the centre today. In 1252, Count Henry V of Luxembourg presented the village of Machern with a charter of freedom. Various conditions were attached to this freedom. In 1357, Duke Wenceslas I granted Grevenmacher the right to organise a weekly market, which contributed greatly to the economic upswing of the small town. In November 1822, 147 houses, around 80 stables and 39 barns burned down in Grevenmacher. The cause of the fire was a pig that had been secretly slaughtered and scorched in Syrgasse the day before.
