Use "transept" in a sentence
"Descending to the church, the Pope proceeds to the northern transept, which is fitted up for the occasion."
"In respect to the latter we would like to investigate whether the form of the building, namely a transept-basilica, corresponds to a martyrium, housing the relics of a saint."
"Covering the foundations and bedrock in the northern part of the transept was a floor of limestone slabs laid in a bed of mortar, some of them still present in the northwest and southeast corners of the space."
