Holy Cross church Joachimsthal, Gothic Revival church in Joachimsthal, Germany.

Holy Cross Church is a plastered classicist hall built from 1735 to 1738 to plans by building inspector Eichler, given a Neo-Gothic reshaping by Karl Friedrich Schinkel after the 1814 town fire. Its light beige facade has twin octagonal towers with pointed-arch louvres and spires, a blue clock face with gold Roman numerals, a round grille window and a pointed-arch doorway. Inside, six cylindrical columns with gold-tinted carved capitals line a single hall with white walls and a red ceiling.

The church was built from 1735 to 1738 to plans by the Brandenburg building inspector Eichler, replacing a Baroque half-timbered church of 1609. A tower added in 1740 in front of the south side gave it the cruciform plan behind its name. After the town fire of 20 April 1814, Karl Friedrich Schinkel directed its rebuilding from 1817 to 1820 in a neo-Gothic form, dropping the tower for a bell gable between two corner turrets.

The name Kreuzkirche refers to the cross-shaped ground plan the church gained after a tower was added to the south side in 1740. Since 1969/70 the north arm has served as a winter church and the south arm as a sacristy, so the interior is oriented toward the east. The congregation still uses the building.

The church stands on Joachimsthal's main square, its south side facing the street; the entrance is through the pointed-arch doorway beneath the round window. Inside, a red runner leads up the central aisle between two rows of three columns to the raised chancel, reached by steps. The interior was reoriented eastward in 1969/70, when the north cross arm became a winter church and the south arm a sacristy.

The church owes its name and cross-shaped plan to a tower added in 1740 in front of the south side, turning the original transverse hall into a cruciform building. Schinkel's 1817–1820 rebuilding then dropped the tower in favour of the bell gable between two corner turrets seen today.
