And there was light...

Inside the lighthouse of Vlieland.
It's open for the public a few hours a day.
The light of these bulbs is increased by special lenses and shine around every few seconds.

This is the lighthouse.

This is a view from the lighthouse.

Last year at the same day we were lucky to visit the famous lighthouse at Terschelling, called "the Brandaris".
This is the view from last year.
