Amsterdam Museum/Tourist Help?

[chargirlgenius]

Jeff’s taking a business trip to Meppen, Germany in a bit (non-specific time, since this is not filtered. Suffice it to say it’s sometime before the end of the year). He can take a few days on either side of the meetings, to do the touristy thing. Meppen is on the far west side of Germany – he’ll actually be flying in and out of Amsterdam. So, Amsterdam or surrounding areas. Any medieval must-sees? I know what Amsterdam is *known* for, but keep in mind that he has a security clearance to keep… ;-)
