The ruins of castle Bodenlaube from 1180 overlook the town from above. The old town hall is a Renaissance design from 1577. The town hall of today is the former mansion of the noble family von Heußlein, built by Johann Dientzenhofer in 1706. The medieval chapel "Marienkapelle" was renewed and enlarged by Balthasar Neumann. The catholic parish church "Herz-Jesu-Kirche" (Church of the Sacred Heart of Jesus) was built in neo-gothic style in 1882 by Andreas Lohrey. The tower is 67 meters high. The "Jakobuskirche" (Church of St. James) was the old catholic parish church of Bad Kissingen. The tower dates back to the 14th century, the church - replacing a medieval predecessor - was built from 1772 to 1775 by Johann Philipp Geigel in classicist style. The Lutheran church "Erlöserkirche" (Church of the Savior) was erected in 1847 according to the plans of the architect Friedrich von Gärtner, and expanded in 1891 according to the plans of August Thiersch. The Russian Orthodox Church of Saint Sergius of Radonesh, consecrated in 1901, was designed by the tsar's architect Viktor Schröter (St. Petersburg) in a neo-byzanthine style and erected by the architect Carl Krampf (Kissingen) for the then very numerous Russian spa guests. The Anglican Church of 1862 for the British spa guests was sold to the Lutheran community in 1953. The dilapidated building was replaced by the Lutheran community center in 1968.
