Notre-Dame-des-Marais in La Ferté-Bernard is a jewel of the flamboyant Gothic style, built on drained marshes between the 14th and 17th centruries. Remarkable as much by its Gothic and Renaissance architecture as by its stained glass windows (late 15th, 16th and 19th century), it also has a 'swallow's nest' organ (1536) and a 15th century alabaster treasure.
Church oriented with a Latin cross plan and Gothic style. Although the western gable façade is very sober, the rest of the exterior decoration of the building is in the flamboyant Gothic style. Inside, the church is bright and the filling of its stained-glass windows reveals skilful late Gothic forms.
References:The Cathedral of Saint Mary Major, often called Lisbon Cathedral or simply the Sé, is a Roman Catholic cathedral located in Lisbon, Portugal. The oldest church in the city, it is the seat of the Patriarchate of Lisbon. The cathedral has survived many earthquakes and has been modified, renovated and restored several times. It is nowadays a mix of different architectural styles.
The site where it stands was the principal mosque of Lisbon when it was an Arab settlement. The construction of the cathedral started around 1150, three years after the city was conquered from the Moors during the Second Crusade. Shortly after the victory the English knight Gilbert of Hastings was named bishop of the city of Lisbon.
One good reason to visit the Cathedral is to visit its charming cloisters located in the back. There are several tombs in the cathedral, the most notable of which is the beautifully sculpted tomb of Lopo Fernandes Pacheco and his wife.
