The current Roma church was preceded by a considerably smaller, Romanesque church. Some fragments from this church have been re-used and incorporated in the façade of the later church. The still extant sacristy is also a remnant of this earlier church.
The earlier church was torn down and successively replaced with Gothic style building between 1215 and 1255. Dendrochronological examinations have shown that the latest additions were made in 1280. The nave and choir seem to have been erected during a single period of construction, possibly with the exception for the westernmost part of the nave, which is slightly different in style. A tower was evidently planned for the church but never executed. Influences for the somewhat unusual architecture may have come from nearby Roma Abbey and thus the traditions of Cistercian architecture. The church has remained largely unaltered since the Middle Ages. The large western rose window was however added in the 1880s.
The church seems to have had a special function. It was built close to the location of the thing of all of Gotland, and not far from a Cistercian monastery, Roma Abbey. Unlike a regular church, it had five entrances (instead of three) and its architecture differs from other churches on Gotland. The likeness of the church with that of the Dominicans in Visby (now ruined) is noticeable. There is therefore reason to believe that the church may have been used by the Dominicans, possibly to preach for crusades against non-Christians in what is today the Baltic states.
The interior is characterised by the renovation in Neo-Gothic style from 1902. The interior is relatively dark, and few medieval furnishings survive. The altarpiece and the pews date from 1902. An older altarpiece has been transferred to one of the nave walls; it dates from 1656. A few medieval tombstones are displayed in the church, and the baptismal font is also medieval. Dating from the 13th century, it has no equivalents on Gotland but has more in common with baptismal fonts from Småland and Östergötland from the time.
In the cemetery, there is a bell tower in which three bells hang. Before 1929, these bells belonged to the Swedish-speaking minority village of Gammalsvenskby in Ukraine.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
