Welcome to the Virtual Record Treasury — Ireland’s National Platform for Digital History and Heritage

VRTI is an all-island and international research partnership.

As Ireland’s National Platform for Digital History and Heritage, we are harnessing advanced technologies to create a shared digital infrastructure for research on Ireland’s deep history. This is an ever-growing, open-access resource, freely and permanently available online to all those interested in Ireland’s deep history, at home and abroad.
