Secondo voi un vasto complesso conventuale può essere costruito su una palude? Ebbene sì, un esempio di tale costruzione lo troveremo nel paesaggio pittoresco della Boemia occidentale, in un piccolo borgo chiamato Plasy. Il monastero cistercense, fondato nel XII secolo, giace su un suolo paludoso, precisamente su oltre cinquemila palafitte di quercia. All’interno della struttura vi è una piscina barocca che non deve mai prosciugarsi, altrimenti l’edificio correrebbe il rischio di crollare. Il legno di quercia insieme all’acqua tiene meglio delle fondamenta in calcestruzzo. Potete ammirare i parametri tecnici della struttura e anche la progettazione architettonica degli architetti J. B. Mathey e J. B. Santini-Aichel, come anche la mostra dedicata alla farmaceutica. La ciliegina sulla torta è rappresentata dalla scala a mensola barocca di Santini, che non è solo bella, ma anche molto fotogenica.
The tour of the Plasy Monastery in West Bohemia near Plzeň will take you to the residential building of the monks, built in the high Baroque style. The history of the monastery is presented with information about the unusual design of the foundation of the building. The tour will take you to the capitulary hall, the Chapel of St. Bernard and the hospital wing with an exposition of a pharmacy, even with unique Baroque toilets. In addition to that, you will see the library hall, the office of the abbot, the reading room and the winter dining room. The guide will tell you about the history of the monastery as well as about what followed its abolition.
Monastery on waterThe Plasy Monastery is built near a river where the monks in the Middle Ages built an artificial canal leading through the area. They used it to bring water to the mill and drive the lumber mill. The Plasy water system is special thanks to the perfect design of the foundations of the convent, which was reinforced with 5,100 oak poles driven into the ground due to the marshy soil. A wooden grate was placed on the poles and then the walls of the building were built. To prevent the grate from rotting and the building from sinking, water from several sources was brought to the foundation to limit the access to air which de facto caused the wood to petrify. The warning “Aedificium hoc sine aquis ruet” is a message to future generations. Therefore, even today, the height, temperature and quality of water in the two Baroque pools inside the building is checked four times a day.
Santini’s self-supporting staircasesFour self-supporting staircases were built in the convent based on the design of Jan Santini Aichel. Two of them connect the ground floor with the attic and two have three arms and are in the buttresses of the heavenly courtyard. At the bottom part of the three-arm staircases, Santini had the “mirrors” built – Baroque pools for checking water in the foundation grate.
Underground systemAlong the heavenly courtyard, 4.5 metres above the ground, a unique heating system of the building is hidden internally. It is a long crooked underground passage that leads to two places on the ground floor of the building. The outlets from this passage lead under the windows on the ground floor. In summer, heat accumulates in the ground around the passage and in the cooler months, the warm air travels to the building through the outlets.
The secret ingredients of Plasy powderOne of the profitable activities of the monastery was the production and sale of Plasy powder. This white mineral tablet made the local monks famous at the beginning of the 18th century, when they even exported it beyond the Czech borders. Processing the main ingredient, a vitriol slate acquired from a quarry in Hromnice, was extremely secret. Pharmacist Lucas Martin Gottlieb guarded the preparation of this stomach medicine very carefully. No wonder, his preparation was not as bitter as most stomach medicines and it was very popular thanks to its flavour.
