Kadriorg Palace and Garden, Tallinn
Concierge.com's insider take:
The park at Kadriorg, just over a mile east of Old Town, is pleasant and wooded, with oak, lilac, and horse chestnut trees. Long a favorite strolling ground of city residents, this green oasis is busy with cyclists and sunbathers on weekends. Italian architect Nicolo Michetti designed these gardens as well as the Baroque Kadriorg Palace for Russia's Peter the Great soon after the czar's conquest of Estonia in the Great Northern War.
Open Tuesdays through Sundays 10 am to 5 pm, May through September; Wednesdays through Sundays 10 am to 5 pm, October through April.
