Tip 1 for the summer is Abbaye Royale de Fontevraud (60 km from our house).
Final resting place of legendary queen, Eleanor of Aquitaine (c.1122-1204), her sons, Richard the Lionheart (Richard Cœur de Lion) (1157-1199), and the heart of John Lackland (c. 1167-1216) (his body rests in Worcester Cathedral), plus much more of the family, the Plantagenets.
Another Fontevraud page with lots of interesting information can be found at Paradox Place France.
So, why not visit this wonderful part of France this summer? (Or later?) ☀
