The former Houthalen mine building was converted into a cleantech service centre for sustainable energy.
In addition, Greenville is also a visitors centre where you can come as an individual visitor on every weekday from 9am to 5pm for a walk through time.
You begin on the ground floor with an exhibition on the mining past. Via the open glass stairwell you go to the first floor with installations regarding the future in the area of energy and materials.
From 5 people upwards you can request a 'tour for groups'.
In addition, every weekday between 12pm and 1.30pm you can visit the company restaurant where you can have a reasonably priced but still wonderful cheap lunch.
