Our 4th port of call was Tallinn Estonia. Tallinn's claim to fame is that its the best preserved medieval town in the world. Our ship arrived in Tallinn about 7am and departed at 1pm so there was only a few short hours to stroll around the city. Fortunately Tallinn is a very compact city (see above photo) which can be seen in a few short hours. Given the short time we did our own sightseeing strolling through the medieval town. A truly enjoyable time.
