Every little town in the Netherlands has it's own feast or something like it. Here it's called: Dag van Lauwe which means: Day of the Town.
Lauwe is dialect for Beneden Leeuwen.
This is a day full of festivities: A lot of attractions for kids, a market, musicstages, demonstrations of fire brigade etc.
And a special event:
Maas en Waalse Buikschuifkampioenschappen
Translated: Regional bellysliding Championships.
The trick is to slide as far on your belly as you can and as fast as you can! The one with the longest distance in the fastest time wins!
This event is normally celebrated in the first weekend of july!
Each year in approx. february Carnaval is celebrated.
Beneden Leeuwen has one of the biggest parades in the province of Gelderland. The parade almost lasts for 2 hours.
All kinds of subjects are mentioned in the parade, like politics, partying, sayings, public figures, past events etc.
The people of Beneden Leeuwen have a different name in carnavalstime:" Broaiers".
Don't ask me the specific explanation of it I wouldn't know. At least not at the moment, I will come back to you with the answer.
