High Places in Amsterdam...

Next we hopped onto the metro and got off at Rokin, which has incredible displays alongside the escalators showing many of the 700,000 archaeological items uncovered during the 16 years of construction of that north-south line.

I included a photo of a display on my blog back in January, but couldn’t resist including some more since they really make this station fascinating.

Our final stop for Open Tower Day was Blue Amsterdam, a rooftop café in the center of Amsterdam.

The views were fantastic...

...and we were lucky enough to get a table for drinks and friets. I enjoyed having my first, of likely to be many, pornstar martinis.
