The former monastery of Santo Domingo/Museo de la Laca (Lacquerware Museum) is located in the city of Chiapa de Corzo, Chiapas, Mexico.
 The monastery with its church was built in the 16th century, with the monastery secularized later.
 The church retains its original function.
 The building with two courtyards was restored between 1999 and 2002 to become a community and cultural center, with the Museo de la Laca, founded in 1952, moved inside to take up much of the upper floor.
 This museum contains about 450 pieces from various parts of Mexico and Asia, mostly made in the 20th century.
 The complex also contains halls with permanent and temporary exhibits along with an auditorium and various types of workshops.
Sant Pere de les Maleses is a Benedictine cave monastery in the municipality of La Pobla de Segur, Pallars Jussà, in the Province of Lleida, Catalonia, Spain.
 the monastery was first mentioned in 868 when it was dedicated to St. Andrew and was donated to St. Vincent of Oveix, the abbot of Attila.
 During the tenth or eleventh century it ceased to be owned by Oveix and was rededicated to St. Peter.
 It later fell under ownership of Santa Maria de Gerri, and lost its status as a monastery.
 It was secularized in 1592 and from then on became a simple church.
The Protestant Reformation in Switzerland was promoted initially by Huldrych Zwingli, who gained the support of the magistrate (Mark Reust) and population of Zürich in the 1520s.
 It led to significant changes in civil life and state matters in Zürich and spread to several other cantons of the Old Swiss Confederacy.
 Seven cantons remained Roman Catholic, though, which led to inter-cantonal wars known as the Wars of Kappel.
 After the victory of the Catholic cantons in 1531, they proceeded to institute counter-reformatory policies in some regions.
 The schism and distrust between Catholic and Protestant cantons would define their interior politics and paralyse any common foreign policy until well into the 18th century.
Schlierbach Abbey (German: "Stift Schlierbach" ) is a Cistercian monastery in Schlierbach, Austria founded in 1355, and rebuilt in the last quarter of the 17th century.
 The original foundation was a convent for nuns, abandoned around 1556 during the Protestant Reformation.
 The abbey was reoccupied as a monastery in 1620, and rebuilt in magnificent baroque style between 1672 and 1712.
 The monastery again went into decline with the upheavals before, during and after the Napoleonic era.
 It recovered only towards the end of the 19th century.
 In the 20th century the abbey established a viable economy based on a glass works, school, cheese manufacturing and other enterprises.
 The abbey is open to visitors, who may take tours, attend workshops and dine at the monastery restaurant.
Saulseat or Soulseat Abbey was a Premonstratensian monastic community located in Wigtownshire, Galloway, in the Gaelic-speaking south-west of Scotland.
 It was regarded as the first and the senior Premonstratensian house in the Kingdom of Scotland.
 There is some evidence that Soulseat Abbey is "Viride Stagnum" ("green loch"), that is, the Cistercian monastery founded by St Malachy somewhere in Galloway in 1148.
 The name comes from the Gaelic word "Sabhal", a word with many religious and monastic connotations.
 Perhaps because of Anglophone folk etymology, the name came to imply a connection to both Saul and the soul, taking the Latin form Sedes Animarum ("Seat of the Spirit").
 The site of Soulseat Abbey (now a mound with five 16th century gravestones thereon) is on the promontory of a loch with a very narrow isthmus, thus perhaps fitting the description.
 The Premonstratensian establishment certainly occurred before the death of King Fergus of Galloway, which took place in 1161.
 The "Obituary of Prémontré" lists both King Fergus and Christian, bishop of Galloway (1154-86), as joint founders.
 Probably because of the abbey's cultural isolation from Lowland Scotland, almost none of the abbots are known by name before the 15th century.
 It is known though that the abbey suffered devastation from wars in the 14th century.
 Control of the abbey became secularized in the 15th century, and even more so after the Scottish Reformation.
 In 1630, it was taken over by the parsonage of Portpatrick.
Lehnin Abbey (German: "Kloster Lehnin" ) is a former Cistercian monastery in Lehnin in Brandenburg, Germany.
 Founded in 1180 and secularized during the Protestant Reformation in 1542, it has accommodated the "Luise-Henrietten-Stift", a Protestant deaconesses' house since 1911.
 The foundation of the monastery in the newly established Margraviate of Brandenburg was an important step in the high medieval German "Ostsiedlung"; today the extended Romanesque and Gothic brickstone buildings, largely restored in the 1870s, are a significant part of Brandenburg's cultural heritage.
Sant Pere del Burgal is a Romanesque Benedictine monastery in Escaló, in the municipality of La Guingueta d'Àneu, Pallars Sobirà, Catalonia, Spain.
 The monastery was first mentioned in a precept of Count Raymond of Toulouse in 859.
 It later became a priory of the abbey of Roussillon.
 It fell into decline and was secularized in 1570 and confiscated in 1835.
 It contains frescoes dated to the 11th century.
Nikola Stepanić Selnički (, Hungarian: "Zelniczey IV.
 Miklós" ) was a Catholic bishop of the Roman Catholic Diocese of Pécs (1596-1598) and Roman Catholic Archdiocese of Zagreb (1598-1602).
 With his 1598 and 1599 activities aimed to impose his feudal authority over Serbs who populated a year earlier vast territories in Slavonia, abandoned for more than 40 years, he initiated the "Vlach question".
Ter Apel Monastery (Dutch: "Klooster Ter Apel" ) is a former monastery in the village of Ter Apel in the northeastern Dutch province of Groningen.
 It is the only monastery in the larger area of Friesland and Groningen that survived the Reformation in a decent condition, and the only remaining rural monastery from the Middle Ages in the Netherlands.
 The convent buildings house a museum for monastery and church history and for religious art, as well as two contemporary art galleries.
 The former lay church of the monastery still functions as a reformed church.
Königsfelden Monastery is a former Franciscan double monastery, which housed both a community of Poor Clare nuns and one of Franciscan friars, living in separate wings, in the municipality of Windisch in the canton of Aargau in Switzerland.
 It was founded in 1308 by the Habsburgs.
 In the course of the Protestant Reformation in Switzerland in 1528 it was secularized, and the complex was then the residence of the bailiffs of Bern.
