This depends a bit on time period and region, but you could take a look at the art-history museum vienna for costumes and stuff:
https://www.khm.at/en/visit/collections/imperial-armoury/selected-masterpieces/

They also have a nice image library:

And the german castle organizations website. From there you could follow links to basically any major castle or palace in europe:
https://www.burgen.de/deutschland/burgen-schloesser-in-deutschland/
I don’t know if this is available in english, but it should work just fine if you put the url in google translate.
