What Archol does

Archol bv (Archeologisch Onderzoek Leiden BV) is a Netherlands-based archaeological research firm founded in 1997 and headquartered on the campus of Universiteit Leiden in Leiden. The company is wholly owned by Leiden University and operates as the university's independent archaeological research bureau, providing end-to-end archaeological services from initial advisory and desk-based research (bureauonderzoek) through borehole investigations (booronderzoek), trial trenching (proefsleuven), full excavations (opgraving), and archaeological supervision (archeologische begeleiding), complemented by specialized material studies including archaeobotany, physical anthropology, flint and natural stone analysis, physical geography, use-wear analysis, and wood and charcoal research, plus digitization of analog field drawings and GIS support.

The firm serves primarily the Dutch public sector (rijksoverheid, provincial and municipal authorities) along with private developers and businesses that require archaeological assessments for permitting under the Erfgoedwet and Omgevingswet. It maintains BRL SIKB 4000, VCA** (two-star), and CO2-Prestatieladder level 3 certifications. Technical capabilities include GIS-based mapping, digital field documentation, georeferencing of legacy drawings, and an experimental AI image-recognition capability using deep learning for automated detection of archaeological features such as prehistoric granaries from post-hole patterns.

Archol operates on a project-based, quote-driven professional services model, billing per project based on scope, complexity, and duration. Approximately 25-26 professionals deliver work nationwide across the Netherlands, with a track record of 800+ completed investigations over 28 years. Distribution is direct to client with no resellers; the firm is also expanding into Caribbean Netherlands heritage protection via the 2025-2027 'Proteha mi' project in partnership with Stichting BONAI and Leiden University.
