The Hidden Iron Bracket: How the Loretto Staircase Was Reinforced

For more than a century the Loretto staircase has been sold as completely free-standing — no center pole, no visible support, held up by faith alone.

There’s a small piece of hardware that complicates that story: an S-shaped wrought-iron bracket, added years after the stair was built, quietly tying it to a nearby column.

It’s the detail the brochures leave out, and it’s genuinely interesting — here’s what it is, who found it, and what it does (and doesn’t) change.

What is the iron bracket?

It is a small S-shaped wrought-iron brace that connects the outer spiral beam (the outer stringer) of the staircase to one of the columns that holds up the choir loft. In plain terms: it pins the upper part of the stair to something solid, so the structure can’t sway or drift outward over time.

It is not a central pole and it doesn’t carry the whole staircase — but it is, unmistakably, an added support.

Who found it?

Skeptical investigator Joe Nickell documented the bracket when he examined the staircase in 1993, publishing it in his article “Helix to Heaven” (Skeptical Inquirer, 1998).

He noted that he could find no mention of the brace in earlier published accounts — which is exactly why it matters: the popular story had been told for decades as if no such reinforcement existed.

His broader conclusion was that the staircase is “subject to the laws of physics like any other.” The full skeptic-vs-believer accounting is on the debunked-or-miracle page.

There is a date attached to all this, usually left off. The bracket was not part of the original build: it went in around 1887, at the same time railings were finally added by a named craftsman, Phillip August Hesch — the stair had spent its first years with neither. So the sequence is clean: built in the late 1870s to stand on its stringers, given railings and a steadying bracket about a decade later, and only documented by Nickell more than a century after that.

Was the staircase “rickety” before the bracket?

There’s a reasonable read here, and we’ll mark where it’s inference rather than fact. A spiral stair with no central column and a very tight inner radius can flex — springiness is a known trait of helical stairs (the “Slinky” behavior described on the how it works page).

The most natural reason to add an iron brace is that, over years of use, the stair developed enough movement to warrant steadying. So the bracket is best understood not as a sign the stair was failing, but as ordinary, sensible maintenance of an unusually slender structure.

The c.1959 choir-load photo

Against the “it can barely hold itself up” reading is a striking piece of evidence: a photograph from around 1959 shows at least twenty choir members standing on the staircase at once.

That’s real, distributed human load — strong testimony that the structure was sound well before and after any reinforcement. The honest picture is a stair that was genuinely capable on its own, and was later given a modest assist for longevity.

Does the bracket “debunk” the miracle?

It debunks one specific claim — that the stair is wholly unsupported — and nothing more. The wood findings, the flawless joinery, and the vanished carpenter are all untouched by a later iron brace.

If anything, the bracket makes the original feat more impressive: the stair carried real loads for decades before anyone felt the need to add so much as a single piece of iron.
