Dendrochronological dating carried out by Dr. biol. Māris Zunde at the Dendrochronology Laboratory of the Institute of Latvian History at the University of Latvia has confirmed and clarified that the construction of the Valmiera Old Pharmacy was completed in 1736. Consequently, it has been confirmed that the Valmiera Old Pharmacy, which is mentioned in sources as the oldest wooden building in Valmiera, is also the oldest surviving wooden building in Latvian towns, constructed using the most archaic building method. It is known that a pharmacy operated in the building from 1756 until 1965.
