A fitting insertion into the landscape, the Mass Extinction Monitoring Observatory (MEMO) project presents an opportunity to revitalise the old Bowers Quarry and to draw attention back to the natural beauty and craftsmanship of Portland. MEMO, as an devised journey, will explore the relationship between interior and exterior, landscape and enclosure. It will comprise a monument to the world’s extinct species and an adjacent biodiversity education centre. Conceived as a continuous spiral of stone, it will be carved with images of the 860 species assessed as extinct since the dodo. The monument itself will be a growing testament and constant reminder to the fragility of life with more stones added when species become extinct. The bell of diversity, placed in the centre of the monument, will be rung annually on the international day of biodiversity and to mark further species becoming extinct. Sited on the Isle of Portland on the South coast of Britain, each creature will be immortalised in stone along the circular ramp that leads to the top of the 100 foot high Bowers Quarry observatory. Visitors will then walk back down the outside of the ramp to ground level.
