If you’re concerned about the future of the iconic Notre Dame cathedral, following the devastating fire in April 2019, there’s good news – the French senate has recently voted to rebuild the cathedral in medieval style. Difficulties have emerged, however, regarding the roof of the cathedral – which was built out of 800-year-old oaks. There are concerns that there might not be enough oaks extant to rebuild the roof – though some historians have asserted that the Baltic states might hold enough tall trees.
