Tallinn, Estonia’s capital on the Baltic Sea, is the country’s cultural hub. It retains its walled, cobblestoned Old Town, home to cafes and shops, as well as Kiek in de Kök, a 15th-century defensive tower. Its Gothic Town Hall, built in the 13th century and with a 64m-high tower, sits in historic Tallinn’s main square. St. Nicholas Church is a 13th-century landmark exhibiting ecclesiastical art.
