Alsike Church stands by a formerly important sea-route linking
Uppsala,
Sigtuna and
Stockholm, in an area characterised by its old
cultural landscape. Although the oldest parts of the presently visible church date from the 13th century, it was probably pre-dated by an earlier
wooden church. The church is constructed largely in
brick, a material not usually used in medieval churches in Uppland (
fieldstone was often the material of choice). The use of brick may be explained by the vicinity to the more costly churches in
Sigtuna or
Sko Abbey near
Skokloster Castle (
Skoklosters slott). The main part of the church was probably built circa 1250-1350. The tower and the
church porch date from the 15th century, and during the same century the church was also equipped with
mural-decorated vaults; due to later damage these have been rebuilt and only fragments of the murals still remain. The church was rebuilt during the mid-19th century. Two
transepts were added, and the exterior whitewashed. Inside the church was equipped with a new
pulpit and new
pews. In 1910-11, the church was redecorated internally with paintings in
Art Nouveau style by architect
Sigurd Curman (1879-1966). During repairs in 1947 a
runestone was discovered in the church; it is displayed at the church entrance.{{cite web|url= https://sok.riksarkivet.se/sbl/Presentation.aspx?id=15743 |title= J Sigurd Curman The church is characterised by a mix of
medieval and
neoclassical styles as a result of the reconstruction during the 19th century. Among the furnishings, a
Venetian crucifix from 1600 and a figure of Christ from the 15th century are noteworthy. ==References==
