Secrets and hidden rooms
A count is not a checklist
The map tool counts 257 secret passages. This page will not pretend to name them. What it will do is sort the secrets that have a name and a reason to visit. Smash breaks floors and some walls. Halo of Light, from Holy Light, passes Chaos Shards. Those two skills are the keys to most 'why won't this open' moments.
The three eye relics open the Gate of Flesh for Mammon. Alucard's Tower sits behind blue flames above the Bridge of Knowledge. The fourth organ melody, read from candles, gives War and Famine. A trophy asks you to break 666 candles.
High-value rooms already written up
If you want a room with a page, use Alucard's tower, the organ, the planetarium, Lisa's Laboratory, the Tomb of the Noble Queen, and Belmont Manor. The rest of the 257 are map pins this site is not copying. A short list of named rooms is more useful than a counterfeit atlas.
What I ran into
Two hundred and fifty-seven is a dare to pad a page. I listed the secrets I could send someone to by name. The number stays as a number, with the source next to it.
