The starkly beautiful Gothic Church of St. James with its slender, 86 m tall tower, is a defining landmark on the Kutná Hora skyline. It is the oldest church in town. Its construction began in 1330 and ended in 1420. The church was originally projected with two towers but it soon turned out that the ground beneath was too unstable due to silver mining to hold both. The unfinished part of the second tower is clearly visible on the church exterior.
