Kappel Abbey is first mentioned in 1185. The abbey was founded by the Freiherr of Eschenbach. The name was derived from a chapel in which, according to a foundation legend, hermits used to live. Between the 13th to 15th Centuries the Abbey received several Imperial and Royal privileges.
On the site of the original church (of which parts are preserved in the present structure), a new church was started in about 1255. This early gothic building wouldn't be completed until the early 14th century. The oldest part of the monastery is the so-called core of the administration buildings, which were probably built in 1209/10 as a hospital (later the residence of the abbot and the prior).
The spiritual and economic golden-age lasted until the middle of the 14th century. Through donations from the landed gentry, purchase and exchange the Abbey had numerous, widely scattered properties. With the help of a number of lay brothers, the Abbey ran a number of businesses. These included a vineyard on Lake Zurich and granges in Wollishofen and Zug. In the 15th Century the Abbey lost the use of most of these distant businesses, they were limited to products produced at the Abbey and a local dairy.
Due of the involvement of Walters IV von Eschenbach, all the Eschenbach possessions were confiscated by the Habsburgs in 1309. In 1339 they were all placed under the authority of the Lords of Hallwyl. Increasingly, it fell under Zurich's authority, and after 1473 the monastic economy was under the direct supervision of the Zurich City Council. In the Old Zurich War, the Swiss Confederation plundered the monastery, whose monks had fled to Zurich. In 1493, a fire damaged the convent building. In the early 16th century the Reformation was gradually introduced. In 1527 the monastery was abolished, and its property was taken over by the city of Zurich.
Following the Reformation the monastery became property of the Canton of Zurich. As of 1834 the buildings were used for social purposes. Since 1983, the cantonal Reformed church as a spiritual retreat. Today it houses a hotel.References:
The Kalozha church of Saints Boris and Gleb is the oldest extant structure in Hrodna. It is the only surviving monument of ancient Black Ruthenian architecture, distinguished from other Orthodox churches by prolific use of polychrome faceted stones of blue, green or red tint which could be arranged to form crosses or other figures on the wall.
The church is a cross-domed building supported by six circular pillars. The outside is articulated with projecting pilasters, which have rounded corners, as does the building itself. The ante-nave contains the choir loft, accessed by a narrow gradatory in the western wall. Two other stairs were discovered in the walls of the side apses; their purpose is not clear. The floor is lined with ceramic tiles forming decorative patterns. The interior was lined with innumerable built-in pitchers, which usually serve in Eastern Orthodox churches as resonators but in this case were scored to produce decorative effects. For this reason, the central nave has never been painted.
The church was built before 1183 and survived intact, depicted in the 1840s by Michał Kulesza, until 1853, when the south wall collapsed, due to its perilous location on the high bank of the Neman. During restoration works, some fragments of 12th-century frescoes were discovered in the apses. Remains of four other churches in the same style, decorated with pitchers and coloured stones instead of frescoes, were discovered in Hrodna and Vaŭkavysk. They all date back to the turn of the 13th century, as do remains of the first stone palace in the Old Hrodna Castle.
In 2004, the church was included in the Tentative List of UNESCO"s World Heritage Sites.
