Ernst Bernhard Lohrmann (30 June 1803 — 17 June 1870)[1] was a German-Finnish architect born and educated in Germany but practising mainly in the Grand Duchy of Finland, where he is known especially as a designer of public buildings and more than 20 churches, many in the late Empire and Gothic Revival styles.

[2] Lohrmann also held the position of Intendant of the National Board of Public Building, following the death in 1840 of his predecessor and compatriot Carl Ludvig Engel.

[2][1] In that role, Lohrmann is credited with considerably developing and systematising the Board's operations, as well as seeing through to completion many of Engel's unfinished designs.
