Schloss Artstetten

[andigger]

I am going to be in Austria near the castle this spring and definitely want to stop by to see the crypt.  I've looked at the Trip Advisor reviews and the responses seem tepid at best (although I don't look to that forum for the history geek perspective).  I'm wondering if anyone here has been to Artstetten, is it worth the entrance fee, is the museum that interesting?  I can read enough German to get the main ideas, but I also don't want to pay 10+ euros to see a couple graves either.

Thanks
