- The Castlevania Dungeon - One of the oldest remaining Castlevania sites. The forums have tons of hidden gems.
- Mr. P's Castlevania Realm - Probably the best non-wiki source for Castlevania information on the 'net, with a stunning homepage to boot.
- Vampire Killer - Has Ayami Kojima's entire artbook scanned, as well as a whole bunch of other stuff.
- Castlevania Web Portal - Konami's official Castlevania page. It's mostly product information.
