east containing three lancet windows, but also a general tendency towards a relatively austere architecture. Inside, these churches were probably all decorated with murals, but very few of these have been preserved. A greater number of Romanesque furnishings have been preserved. Workshops specialising in making sculpted baptismal fonts were established on Gotland during the 12th century and not only supplied the churches on Gotland with decorated fonts, but also exported fonts to the entire Baltic region. Several of these workshops have been given notnames by later art historians, such as Majestatis and Byzantios, while other labels, such as Sigraf and Hegvald, derive from inscriptions found on the fonts. A number of wooden sculptures have also been preserved from this time, including the Viklau Madonna, one of the most well-preserved 12th-century wooden sculptures in Europe, and a number of rood crosses from the same workshop. A boom in church building began on Gotland around 1225. New churches were erected and older churches were rebuilt. During this period, a local variant of Gothic architecture would replace the earlier Romanesque style. The churches became considerably larger, with vaults supported by pillars and divided into several bays. Apses were no longer built. Another peculiarity is that the north side of the churches almost always lacked windows; whether for practical, religious or superstitious reasons is not known. Stylistically, a conservative Early Gothic style, still strongly reminiscent of Romanesque through its heavy volumes and often round arches, would prevail until the end of the 13th century. Influences came from Westphalia, conveyed via Visby, an indication of the trade connections of the time. At the end of the 13th and early 14th century the style shifted towards what is often referred to as High Gothic In contrast to earlier churches, these churches have decidedly Gothic forms such as larger, pointed arch windows and more slender pillars supporting higher vaults. Several of them are decorated with murals. Also more stained glass windows are preserved from this period, and the churches of Gotland contain the largest amount of medieval stained glass in Sweden, with Lye Church containing the largest intact set in the Nordic countries. From 1320 until around 1360, the last great building period took place on Gotland. Stylistically, there is a change towards a heavier architecture, which in Swedish literature sometimes is referred to as "counter-Gothic" (). While purely Gothic in details such as windows and portals,
