THE BASILICA OF ST. MARIA DEI SERVI
It was founded by a group of monks from Montesenario called Maria’s Servants around 1230, but the construction was very long and the front of the basilica is unfinished. The inside is completely different from the outside: there are three luminous and spacious Renaissance styled naves, with many interesting paintings and ancient frescoes, such as a Madonna with Child by the Florentine Coppo di Marcovaldo (1261 ),taken prisoner by the Sienese during the battle of Montaperti, and The slaughter of the innocents by Matteo di Giovanni ( 1491 ).
You can find the basilica in the south part of the city in Via dei Servi, close to Porta Romana.
