Board the ss Rotterdam!

3e Katendrechtsehoofd 25,

For this year's EuRuKo we managed to secure a unique location in Rotterdam: the ss Rotterdam. A ship with a rich history now permanently docked right in the smack center of Rotterdam.

The event space is wheelchair accessible.

Book your accommodation on the ship (yes, really).


The schedule is subject to change.
