The Former
Benedictine Beinwil Abbey is listed as a Swiss
heritage site of national significance. The entire site of Beinwil Abbey is part of the
Inventory of Swiss Heritage Sites. The abbey was founded around 1100, probably by the local nobility. It was first mentioned in 1147. After conflicts arising from the territorial claims of the towns of
Solothurn and
Basel against the
Counts of Thierstein, who acted as the abbey's
Vögte (lords protectors), it was burnt down in 1445. After Beinwil had been taken over by Solothurn in 1519, the town authorities impounded much of the abbey's possessions. By the 16th century, only a few monks were left in the abbey, and it was formally dissolved in 1554. A small community remained, the care of which was assumed firstly by
Einsiedeln Abbey, in 1589, and then, from 1622, by
Rheinau Abbey. As no monastic revival could be achieved due to the remote location, it was decided to re-settle the community at
Mariastein Abbey, a new foundation in a pilgrimage center, which took place in 1648. In anticipation of this, Mariastein became a member of the
Swiss Congregation, now part of the
Benedictine Confederation. From Mariastein, at the end of the 18th century, it was at length possible to revive Beinwil, and at that time the church and the monastic premises were rebuilt. The abbey was however suppressed in 1874 by
plebiscite during the
Kulturkampf, and the community of Mariastein went into exile. The abbey church, dedicated to Saint
Vincent of Saragossa, was destroyed by fire in 1978. It has now been comprehensively restored and a high altar has been installed, dated about 1700, from
Bellwald. The former abbey was used as an
ecumenical conference and retreat center from 1982 until 2018. It is now an Orthodox Monastery. ==Politics==
