In which city is this abbey church located where Saint Fulrad was the abbot?
Basilica of St Denis The Basilica of Saint Denis (French: "Basilique royale de Saint-Denis" , or simply "Basilique Saint-Denis") is a large medieval abbey church in the city of Saint-Denis, now a northern suburb of Paris. The building is of unique importance historically and architecturally as its choir, completed in 1144, shows the first use of all of the elements of Gothic architecture.
Territorial abbey A territorial abbey (or territorial abbacy) is a particular church of the Catholic Church comprising defined territory which is not part of a diocese but surrounds an abbey or monastery whose abbot or superior functions as ordinary for all Catholics and parishes in the territory. Such an abbot is called a territorial abbot or abbot "nullius diœceseos (abbreviated abbot "nullius and Latin for "abbot of no diocese"). A territorial abbot thus differs from an ordinary abbot, who exercises authority only within the monastery's walls or to monks or canons who have taken their vows there. A territorial abbot is equivalent to a bishop in Catholic canon law.
