The Berlin Cathedral dates back to 1465, and due to the St. Erasmus Chapel, it became a collegiate church. With the Reformation of 1539, Martin Luther changed it to a Lutheran Church and with the dissolving of the collegiate church, it was now the highest in Cölln, situated on the Spree. It became Calvinist (Wikipedia Article) in 1613 before the ruins were taken down in 1750 as Frederick the Great required a new Baroque building. It was converted into the building it is today in 1822 by Karl Friedrich Schinkel, with the final design taking place by 1905, and the building that can be seen today is the one that was renovated after World War II.
