Grand Duchess Maria Teresa shared a selection of the royal couple's favourite places in Luxembourg in a post on her Facebook page.

From the sun-lit vineyards of the Moselle, to the historical Corniche in the capital, to the medieval castle in Vianden and the serene walking trails amid the Müllerthal rock formations.

The post was accompanied by previously unreleased images of Grand Duke Henri and Grand Duchess Maria Theresa enjoying their favourite spots.

"These are places which are particularly important to the Grand Ducal couple, and where they like to spend quiet moments together," the post read.
