Preparations for the internal refurbishment of Arsenaal began in 2016, when the Asian Library moved to the University Library. The refurbishment will encompass the interior and installations. The result will be modern work places, teaching and study areas and attractive meeting places. The exterior of the building will remain unchanged. The refurbishment is expected to begin in January 2019.
Some of the employees of the LUCAS institutes (Leiden University Center for the Arts in Society) and LUCL (Leiden University Center for Linguistics) will move into the building after the renovation.
