There seems to be more space inside than there would seem to be from outside. "The outside looks like a townhouse, while past a veil of magical force on the inside are various rooms with various mystical artifacts", as one source put it.

The building's depiction has varied over the years but some elements remain consistent. It was noted that as of 2016, the location could be found on Google Maps. In the comics, the building was said to have been built upon the site of pagan sacrifices, and before that Native American rituals, and is a focal point for supernatural energies. It is "in the heart of New York City's Greenwich Village." Contrary to fan theories that this address was meant to invoke 221B Baker Street, the fictional domicile of Sherlock Holmes, it was actually a reference to the address of an apartment shared in the 1960s by Roy Thomas and Gary Friedrich. The Sanctum Sanctorum is a three-story townhouse located at 177A Bleecker Street. But it's pretty, has a couple of cool death scenes (the "hair" moment is horrible) and it's much, much shorter than The Abyss.177 Bleecker Street, New York City in 2013. Yes, the cave is surprisingly well-lit and yes, saying "what could possibly go wrong" before abseiling into the bowels of the earth is utterly stupid. From the ethereal splendour of a vast underwater cave to the pockets of air bubbling like mercury on the rocky ceiling, it's a feast for the eyes even when it leaves the brain starving. That said, there's some eerily beautiful moments of utter horror to be found. So when Grrr, Aaargh (Frank MacGuire), Whinging Son (Rhys Wakefield), Millionaire Jerk (Ioan Gruffudd), Comic Relief (Dan Wylie), Woman (Alice Parkinson) and Expendable Foreigner (Cramer Cain) find themselves trapped underground, you'll be more interested in how they're going to die than in the clunky dialogue.

In fact, it's not that surprising that as his sticky fingers are all over the post-production and cinematography, this feels like a James Cameron flick where the script never got past the first draft.

And you'll probably be able to figure out what order they'll run out of oxygen in as well. Playing out like The Descent with more water and no monsters, it's a beautifully shot survival flick but it's populated with characters so bland that you won't care one bit if they survive or not. For a film that goes so deep underground, Sanctum is a remarkably shallow experience.
