Question: In which city is this abbey church located where Saint Fulrad was the abbot?

Saint Fulrad (French: "Fulrade" ; Latin: "Fulradus" ) was born in 710 into a wealthy family, and died on July 16, 784 as the Abbot of St. Denis.  He was the counselor of both Pippin and Charlemagne.  Historians see Fulrad as important due to his significance in the rise of the Frankish Kingdom, and the insight he gives into early Carolingian society.  He was noted to have been always on the side on Charlemagne, especially during the attack from the Saxons on Regnum Franserum (Latin for Frankia), and the Royal Mandatum (a royal official of the Carolingian administrative hierarchy).  Other historians have taken a closer look at Fulrad’s interactions with the papacy.  When Fulrad was the counselor of Pepin he was closely in contact with the papacy to gain approval for Pepin’s appoint as King of the Franks.  During his time under Charlemagne, he had dealings with the papacy again for different reasons.  When he became Abbot of St. Denis (N.E of Paris), Fulrad’s life became important in the lives of distinct historical figures in various ways during his period as St. Denis’s abbot during the mid-eighth century.  Saint Fulrad’s Feast Day is on July 16. <SEP> The Abbey of Saint Gall (German: Abtei St. Gallen ) is a dissolved abbey (747–1805) in a Roman Catholic religious complex in the city of St. Gallen in Switzerland.  The Carolingian-era monastery has existed since 719 and became an independent principality between 9th and 13th centuries, and was for many centuries one of the chief Benedictine abbeys in Europe.  It was founded by Saint Othmar on the spot where Saint Gall had erected his hermitage.  The library at the Abbey is one of the richest medieval libraries in the world.  The city of St. Gallen originated as an adjoining settlement of the abbey.  Following the secularization of the abbey around 1800 the former Abbey church became a Cathedral in 1848.  Since 1983 the whole remaining abbey precinct has been a UNESCO World Heritage Site. <SEP> The Basilica of Saint-Sernin (Occitan: "Basilica de Sant Sarnin") is a church in Toulouse, France, the former abbey church of the Abbey of Saint-Sernin or St Saturnin.  Apart from the church, none of the abbey buildings remain.  The current church is located on the site of a previous basilica of the 4th century which contained the body of Saint Saturnin or Sernin, the first bishop of Toulouse in c. 250.  Constructed in the Romanesque style between about 1080 and 1120, with construction continuing thereafter, Saint-Sernin is the largest remaining Romanesque building in Europe, if not the world.  The church is particularly noted for the quality and quantity of its Romanesque sculpture.  In 1998 the basilica was added to the UNESCO World Heritage Sites under the description: World Heritage Sites of the Routes of Santiago de Compostela in France. <SEP> 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.
