Las Amangcwaba e-Saint Peter kunye noMarcellin Zibekwe kwiVia Casilina, kwindawo eyayisakuba yiVia Labicana. Ngelo xesha babekwabizwa ngokuba ngamangcwaba aseSanta Elena okanye iiCacacombs zaseSan Tiburzio.
Ukufikelela kula mangcwaba angaphantsi komhlaba kwenziwa kwiparishi ye-Saints Marcelino kunye ne-Pedro ad Duas Lauros, yona, kunye ne-Mausoleum yase-Elena, i-basilica namhlanje engcwatyelwe kwaye amasalela amangcwaba amahashe abodwa enza indawo ebizwa ngokuba yi-Ad Duas Lauros, mhlawumbi ngenxa yemithi emibini ye-laurel eyayikule ndawo.
La mangcwaba, ane-18.000 yeemitha zesikwere, yeyesithathu ngobukhulu eRoma. Kude kube ziinyanga ezimbalwa ezidlulileyo bebevulelekileyo kuphela kuluntu kanye ngonyaka, kodwa ukusukela nge-13 ka-Epreli odlulileyo, banokundwendwelwa rhoqo ngeempelaveki. Indawo ebiyelweyo ibuyiselwe ngokupheleleyo kwaye ihonjiswe ngemizobo yamaKristu yokuqala efana nobunzima bezi mpawu. Ngokuchanekileyo, ngenxa yenkxaso ye-Alieyev Foundation, amagumbi angama-2014 ahonjiswe ngemifanekiso yobuKristu kwiinkulungwane zokuqala abuyiselwa kubuqaqawuli bawo bokuqala.
Igama layo libhekisela kubafeli-nkolo ababini abangamaKristu, uMarcelino noPedro, abathi ngokwesiko bangcwatyelwa apha, kufutshane kakhulu neSan Tiburzio. Ngo-2006, kwafunyanwa amathambo angaphezulu kwewaka, abekwa enye ngaphezulu kwenye kwaye enxibe iimpahla ezazingcwatywe ngazo. Yayiyimpahla entle, enemisonto yegolide, kwaye yayisongelwe ngamashiti, into exhaphakileyo kwimingcwabo yamandulo yamaKrestu.
Lo mmandla uphethwe ngu-Helena waseConstantinople, umama ka-Emperor uConstantine.
