The Church of St. Lawrence / Pyhän Laurin kirkko in Vantaa is a very beautiful medieval church, built around 1450. The distance from my home to the church is about 10 km and my in-laws are buried in its graveyard. Prior to the introduction of Lutheranism into Finland, the church served the Roman Catholic Church. In 1893 the church was largely destroyed by a fire, leaving behind only its stone walls and vaults. Reconstruction was overseen by the renowned Finnish architect Theodor Höijer and the church was reopened the next year. More info at Wikipedia.
Singing Christmas carols in churches in December is very popular in Finland.
This year no singing of carols, also the services are only online.
We have also a habit of taking candles to the graves at Christmas.
