Underwater Cultural Heritage (UCH) is a significant yet underexplored aspect of our global cultural heritage, comprising shipwrecks, submerged settlements, and other artifacts lying beneath our seas and oceans.
Despite its importance, the preservation and study of UCH face numerous challenges due to the harsh marine environment, limited funding, and the complexities of underwater archaeology. These challenges necessitate innovative approaches and collaborative efforts to ensure the effective protection and sustainable use of UCH.
The BCThubs project was conceived to tackle these challenges.

BCThubs
BCThubs (Blue Culture Technology Excellence Hubs) is a Horizon Europe initiative that brings together 15 partners and 5 associated partners from Greece, Malta, Bulgaria, and Italy to strengthen research and innovation capacity in underwater cultural heritage.
The project builds interconnected ‘Excellence Hubs’ that link academia, SMEs, public authorities, and cultural institutions (quadruple helix engagement). Each hub is a structured network of local actors focused on UCH and designed to foster cross-border collaboration. It integrates scientific, societal, economic, and technical efforts to advance technologies and skills for documenting, preserving, and valorising underwater heritage, while boosting innovation, awareness, education and tourism.
With nearly €5 million in EU funding, BCThubs has established a robust and succesful network of Excellence Hubs in Greece, Bulgaria, and Malta.
Key Project Achievements
To give an impression, here are some of the results accomplished through this setup at Malta Hub level:
- Innovative Technology Prototype Development: Significant progress in developing a real-time underwater health and safety monitoring system for divers, enhancing both research capabilities and safety.
- Ecosystem Development: Successful establishment of stakeholder networks and the formulation of legal and operational frameworks to ensure the long-term sustainability of the BCT hubs.
- Capacity Building & Training: The launch of targeted training programmes, including the recent BCThubs Malta Training Camp, which provides early-career professionals with hands-on skills in scientific diving, ROV operations, GIS mapping, and Ocean Literacy—an online self-paced course endorsed by the Intergovernmental Oceanographic Commission (IOC) of UNESCO under the UN Ocean Decade umbrella.
A Model for Replication
The BCThubs project is designed to be adapted and implemented in other coastal regions. Their work includes a model for replication to establish new hubs, ensuring that the project’s impact can extend far beyond its initial geographical scope.
A Vision Recognised
On 28 November 2025, at the 5th WestMED Stakeholder Conference in Tunis, Tunisia, BCThubs was awarded the WestMED Project Award in the category ‘Maritime Clusters.’ This prestigious award recognises outstanding and replicable projects that contribute to a sustainable blue economy in the Western Mediterranean.
Ines Boujmil – BCThubs project coordinator at AquaBioTech Group (on behalf of the Malta HUB):
“Our team is incredibly honoured by this recognition from the WestMED Initiative, this award is a powerful testament to the hard work and dedication of all our partners across Greece, Bulgaria, and Malta. It reinforces our belief that by uniting technology, policy, stakeholder engagement and skills development, we can unlock the immense potential of our blue cultural heritage for the benefit of local communities and the wider Mediterranean region.“

EU’s support for UCH
The European Union strongly supports Underwater Cultural Heritage (UCH) by embedding its protection and valorisation into research funding, marine governance, maritime spatial planning and regional cooperation strategies.
The EU integrates Underwater Cultural Heritage (UCH) mainly through Maritime Spatial Planning (MSP), the Sustainable Blue Economy strategy, and alignment with the UNESCO 2001 Convention on the Protection of the Underwater Cultural Heritage.
The European Climate, Infrastructure and Environment Executive Agency (CINEA) of the European Commission has published a handbook on incorporating underwater cultural heritage into Maritime Spatial Planning practices, addressing relevant initiatives in their different stages of development: from those that are just starting up, to those that are already well-established, and looks at ways to achieve an ideal balance and give a new impetus to the nexus between the protection and preservation of UCH and the development of a sustainable blue economy in European seas.
UCH is treated as both a cultural asset and a spatially managed resource, ensuring it is preserved, valued, and balanced against other sea uses like shipping, energy, and fisheries.
