Principessa, it has nothing to do with Tonga.
Tongeren is the oldest city of Belgium, a place of
pilgrimage. Princess Mathilde and Prince Philippe will
attend a famous coronation ceremony there.

I've read that Tongeren is proud to be the cradle of
Christianity in today's Netherlands and Flanders and
already in the Middle Ages pilgrimages were made to
that town. Every seven years that special celebration
is held, this year for the 17th time and one highlight
are the four processions.
