You'll notice on that blast door map that was just posted the words "sursum corda".

Looked it up:

sursum corda - (Roman Catholic Church) a Latin versicle* meaning `lift up your hearts'

*versicle - a short verse said or sung by a priest or minister in public worship and followed by a response from the congregation

Also, there was Credo nos in fluctu eodem esse which means "I think we're on the same wavelength"

...and there's more:

egrescit medendo means "The treatment is worse than the disease."

Malum consilium quod mutari non potest - "It's a bad plan that can't be changed."

Cogito Ergo Doleo - "I think therefore I am depressed"

Ut sit magna, tamen certe lenta ira deorum est - "The wrath of the gods may be great, but it certainly is slow"

Hic sunt dracones - "Here be Dragons"
