To preserve the architectural finishes of the Chapel, the only floral decorations permitted are altar table arrangements. Bows may be attached to pews with ribbons. Helium balloons are not permitted in the Wren Building. Nothing may be taped, tacked, stapled, nailed or otherwise affixed to the walls, floors, doors, or pews; items may not be hung from the wall sconces.

Articles necessary for the celebration of a religious service may, of course, be used.

Runners and flower petals may not be used on the slate floor of the aisle because of the danger of slipping. The throwing of rice, birdseed etc. is not permitted inside or outside the Chapel.

The pulpit and items in the altar area may not be moved without the prior approval of the building director.

Candles for the candlesticks on the altar will be provided by, and lit and extinguished by, building staff. A unity candle arrangement may be used, but those candles must be placed on the altar table and must be dripless and white or off-white in color. Standing candelabra may not be used in the Chapel. Use of the wall sconces is not permitted. Candles may not be carried when lit.

Vestments, books, and most of the sacred vessels stored in the sacristy are the property of campus religious groups and are not available for use by others without permission of the owners. There is a silver communion service for Chapel weddings which may be used by prior arrangement with the building director.

Following the service all ring boxes, flower wrappings, programs, and other such items must be immediately removed from the sacristy and Chapel. All decorations must be removed from the Chapel at the conclusion of the service, including items placed in the Chapel by florists.
