Question: What was the pantheon used for in the city in where the creator of Fiesole Altarpiece died?

<P0-S0> The Fiesole Altarpiece is a painting by the Italian early Renaissance master Fra Angelico, executed around 1424–1425. <P0-S1> It is housed in the Convent of San Domenico, Fiesole, central Italy. <P0-S2> The background was repainted by Lorenzo di Credi in 1501. <SEP> <P1-S0> it is one of the best - preserved of all ancient roman buildings, in large part because it has been in continuous use throughout its history, and since the 7th century, the pantheon has been used as a church dedicated to ``st. mary and the martyrs ''(latin: santa maria ad martyres) but informally known as`` santa maria rotonda''. <P1-S1> the square in front of the pantheon is called piazza della rotonda. <P1-S2> the pantheon is a state property, ruled by italy's ministry of cultural heritage and activities and tourism through the polo museale del lazio; in 2013 it was visited by over 6 million people. <SEP> <P2-S0> The Pantheon (/ ˈpænθiən / or US: / ˈpænθiɒn /; Latin: Pantheum, from Greek Πάνθειον Pantheion, ``(temple) of all the gods '') is a former Roman temple, now a church, in Rome, Italy, on the site of an earlier temple commissioned by Marcus Agrippa during the reign of Augustus (27 BC -- 14 AD). <P2-S1> The present building was completed by the emperor Hadrian and probably dedicated about 126 AD. <P2-S2> He retained Agrippa's original inscription, which has caused confusion over its date of construction as the original Pantheon burned down, so it is not certain when the present one was built. <SEP> <P3-S0> the gothic altarpiece of santes creus is an altarpiece painted by guerau gener and lluís borrassà between 1407 and 1411. it is one of the key works of the international gothic altarpieces in catalonia, created for the santes creus monastery. <P3-S1> the mnac museum retains the "nativity", crowned by the figure of "st. john the evangelist", and the resurrection of christ, while the rest of the tables are kept in one of the chapels of the cathedral of tarragona. <P3-S2> the altarpiece was commissioned to pere serra but apparently died without starting it. <P3-S3> guerau gener, a connoisseur of valència international gothic, replaced him, but his untimely death made lluís borrassà, one of the major figures in the painting of the first international catalan gothic, to complete the project. <SEP> <P4-S0> In 1445 Pope Eugene IV summoned him to Rome to paint the frescoes of the Chapel of the Holy Sacrament at St Peter's, later demolished by Pope Paul III. <P4-S1> Vasari claims that at this time Fra Angelico was offered the Archbishopric of Florence by Pope Nicholas V, and that he refused it, recommending another friar for the position. <P4-S2> The story seems possible and even likely. <P4-S3> However, if Vasari's date is correct, then the pope must have been Eugene IV and not Nicholas, who was elected Pope only on 6 March 1447. <P4-S4> Moreover, the archbishop in 1446–1459 was the Dominican Antoninus of Florence (Antonio Pierozzi), canonized by Pope Adrian VI in 1523. <P4-S5> In 1447 Fra Angelico was in Orvieto with his pupil, Benozzo Gozzoli, executing works for the Cathedral. <P4-S6> Among his other pupils were Zanobi Strozzi.
