With the high windows the light could shine all the way into the rooms, which made it possible to work on two levels. In 2020, this room features the spacious Study Lounge. -

Information
Named after P.J. Veth
The building was named after Pieter Johannes Veth (1814-1895) in 2006. Veth’s intelligence got him noticed and he was awarded a place at Leiden University to study theology. He also studied languages, namely Hebrew and Arabic. He was awarded a PhD in Leiden in 1840 for his transcription of an Arabic manuscript.
History of the building
The experimental branch of botany, plant physiology, was emerging rapidly at the end of the 19th century. Larger teaching and research laboratories were needed due to the increased interest in the field. Architect Jacob van Lokhorst was commissioned to design a building that would be suitable as a botanic laboratory, teaching space and national herbarium. The new laboratory would be situated by the Hortus, on the site of the old laboratory behind the Academy Building. The construction plan was implemented in phases, so that the research and teaching could continue during the building work. One of the main aims of the plans was to locate the Botanic Laboratory and National Herbarium in one building, while their roles and organisations remained separate.
The Botanic Laboratory on Nonnensteeg 3 was built first, between 1904 and 1908. The new National Herbarium at Nonnensteeg 1 was added in 1914. The buildings were linked by a lower section and were built in neogothic style, identifiable by aspects such as the high pointed windows with flamboyant tracery.
