The Medieval Old Town in Tallinn.

The history of Tallinn is incredibly rich. The first fortress was built on Toompea (the cathedral hill) as early as the mid 11th century. In the middle ages, the town was part of the Hanseatic League. It lay on the cross roads between the Northern Europe and Russia, and prospered enormously. 
Today, the Old Town is visited by thousands of tourists each year. And with good reason - it is well preserved and presented, and since the late 1990s it has been a UNESCO World Cultural Heritage site. 
For a while, we forgot the modern glass and concrete buildings and paved tar roads and wandered the narrow cobblestone streets and alleys of this beautiful medieval part of Tallinn.

An observation platform on Toompea. Later we would climb up to the steeple of St. Olaf's church the children are looking at here.

Inside St. Olaf's church. The steeple of the church was the tallest edifice in the whole of Europe at one time.

Of course, we had to climb to the observation platform of the steeple to see the height for ourselves.

An interesting find in the Old Town.

This house was built long before Christopher Columbus was even born.
