17th century and today often give a Baroque touch to the medieval churches. While the churches on Gotland have attracted interest since at least the 17th century, a more scientific approach to them started only during the 19th century. Art historian Johnny Roosval presented a first systematic study in Die Kirchen Gotlands ("The churches of Gotland"), published in German in 1911. Roosval dated the different churches on Gotland mainly on stylistic grounds. The timeline he established has subsequently been revised in individual cases, both by Roosval and by others. Overall, Roosval's assumptions about the age of the churches on Gotland are still widely accepted. Archaeological examinations in connection with renovations of the churches in particular during the 20th century served to further tweak the dates in individual cases but also to confirm the overall timeline. In a few cases where contemporary scientific methods have been used to examine the churches, radiocarbon dating and to a lesser extent dendrochronology have also lent some support to the established timeline.
