Going to Finland to see Aurora, passing through Helsinki, you can't miss the famous rock church in Northern Europe. When it comes to the architectural art of European churches, Finland is definitely not a name. But in the Finnish capital of Helsinki, there is a church that shocks the whole of Europe, that is, the "rock church" built in the rock, also known as the Tamperio Kio Church, which was completed in 1969 and is Siomar. The elaborate masterpieces of the La Nie brothers are surprisingly constructive. The rock church design is extremely innovative. It is built from the rocky highlands on the residential street. In order not to damage the natural landscape around the church, the Siomara family drilled the rock and the church was built. In natural rock, from the outside of the church, it is difficult to see that this is a church, and there is no cross mark outside the church. The roof of the church is dome-shaped with a hundred radial beams and columns, and is covered with clear glass. The light comes from the outside during the daytime. The interior of the church is very light and completely free of other lighting.
