Every pew in this Catholic cathedral has these cut-out slots. Does anyone know what they’re used for?

The small cut-out slots you see on the back edge of each pew in this Catholic cathedral are not random decorative details, nor are they signs of damage or wear. They actually serve a very practical and thoughtful purpose rooted in the traditions of church architecture and communal worship.

At first glance, the rectangular notch carved into the wooden pew looks like it could be a handle, a design accent, or even a missing piece.

But in reality, these cut-outs are most commonly used to hold or secure kneelers, prayer books, or sometimes personal items during Mass and other services.

Let’s explore the most likely and historically accurate explanations in detail.

1. Support for Folding Kneelers

In many traditional Catholic churches, pews are equipped with kneelers — padded wooden boards attached to the back of the pew in front of you.

During parts of the Mass, especially during prayer or the Eucharistic Prayer, congregants kneel as a sign of reverence.

These kneelers typically fold up when not in use and fold down when needed.

The cut-out slot in the pew often functions as a clearance or fitting space that allows the kneeler mechanism to move smoothly.

In some older cathedral designs, the kneeler’s supporting bar or hinge system partially aligns with these carved slots.

The indentation ensures that the kneeler can lock securely in place or rest evenly when raised.

Without this cut-out, the mechanism might rub against the wood or fail to fold properly.
