The Gradual from the usus antiquior was this:
Locus iste a Deo factus est, inæstimabile sacramentum, irreprehensibilis est. Deus, cui adstat Angelorum chorus, exaudi preces servorum tuorum. Alleluia, alleluia. Adorabo ad templum sanctum tuum: et confitebor nomini tuo. Alleluia.Here is the sublime setting by Anton Bruckner. I have fond memories of singing this for a church consecration.
(I'm prejudiced, but I've not found an English translation that matches the Latin) This place was made by God, a pricelss mystery, it is without reproof. O God, before whom stands the choir of angels, give ear to the prayers of Thy servants. Alleluia, alleluia. I will worship towards Thy holy temple: and I will give glory to Thy name. Alleluia.
