Minster of St. Mary and St. Mark (Münster St. Maria und Markus), Reichenau

There are also many smaller things to discover in the church. The baptismal font, for example, or the confessional, the Pieta or the closed choir. But interestingly not an organ. Probably didn't need the monks and only sang unaccompanied.

St. Mary and St. Mark's Minster with treasury and monastery gardens
The oldest church on the island is St. Mary and St. Mark's Minster, the former monastery church (founded in 724). The simple wooden building of the monastery's founder Pirmin became too small after just a few decades and was replaced by a 40 m long stone building in the 8th century. To the north of this, i.e. opposite the convent buildings that are still visible today, there was a cloister and a two-storey monks' house. These buildings were soon expanded too, because in the middle of the 9th century the island convent had 134 monks.
While this monastery complex has only been preserved in underground traces, we can still trace the stages of development of the abbey church today. The eastern transept and the crossing arches come from the three-aisled cross basilica consecrated in 816, which Abbot Heito I had built. While Heito's crossing building remained unchanged for a long time, the western part of the abbey church was rebuilt several times. The westwork received its current appearance under Abbot Berno. It was consecrated shortly before his death in 1048 in the presence of Emperor Henry III.
After the decline of the abbey, regular monastic life only began again with Abbot Friedrich von Wartenberg (1427-1435). He began building the Gothic choir in the east of the cathedral, which was not completed until the painting in 1555. After incorporation into the diocese of Constance in 1540, the monastery continued to exist as a priory. Prince-Bishop Jakob Fugger had new convent buildings built on the south side of the cathedral from 1605 to 1610. After the complex was completed, the "Old Monastery" on the north side was demolished. The monastery was dissolved in 1757. The Fugger "new" convent buildings now serve as a rectory and the seat of the municipal administration. The winegrowers' association presses Reichenau wine in the spacious cellar.
In the cathedral's treasury, numerous reliquaries and other cult objects from the 5th to 18th centuries can be seen.

Reichenau Monastery Gardens, near the Minster of St. Mary and St. Mark
The Reichenau Monastery, founded in 724, produced two of the most important sources on the garden culture of the Middle Ages: the St. Gallen Monastery Plan and the poem "Hortulus" by the Reichenau monk and later abbot Walahfrid Strabo.
The new monastery gardens interpret these sources, they recreate parts of them and establish a connection to the island's current garden culture. The gardens comprise three areas, all of which are located within the old monastery wall in the so-called "quiet district" of the former monastery and some of which have been archaeologically proven: the cloister, the Hortuli (gardens) with the herb garden and the monk's cemetery with orchard.
