Sea wall tiles

Falmouth Harbour has worked with Cornish environmental charity Our Only World in partnership with Falmouth Town Council and ARC Marine to install sea wall tiles on to the east wall of Church Street Car Park

What is the Falmouth Seawall tiles project??

Harbour walls are generally quite flat with few places for animals to attach to and live within. The tiles we have installed have been designed to create more places for animals and plants to live and grow. It is expected this will increase the number of different plants and animals that can inhabit the wall and therefore increase biodiversity which is important as diversity within ecosystems increases their resilience.

Our Only World provided the funding to purchase the tiles and they have developed a video explaining their wider project. It is available to view here.



Why is it important

Falmouth is home to a wide variety of habitats including seagrass, maerl, sand, mud and rocky shore. These tiles most resemble that of the rocky shore habitat which is sometimes replaced by man made structures and may be increasingly lost due to sea level rise.

As the tiles resemble the rocky shore it will be interesting to see whether they attract similar plants and animals.

How do Habitiles contribute?

Habitiles have been designed by ARC Marine to withstand tidal forces whilst creating greater habitat complexity than traditional sea walls. They encourage settlement and colonisation to increase intertidal and marine biodiversity. The tiles are made from a low carbon concrete and have been tested to ensure they do not harm the marine environment.




A baseline biodiversity survey was undertaken in March 2023 to allow us to establish a baseline for biodiversity in this area. We plan to repeat the survey next year to quantify whether biodiversity has increased.

We plan to complete regular surveys with the help of local University and college students and hope to share the survey results on this page so watch this space.
