Alexander Nevsky Cathedral
This area was once an almost separate town, heavily fortified, and has always been the seat of whatever power that has ruled Estonia. The hill occupies an easily defensible site overlooking the surrounding districts. The major attractions are the medieval [[Toompea Castle]] (today housing the Estonian Parliament, the "[[Riigikogu]]"), the Lutheran [[St Mary's Cathedral, Tallinn|St Mary's Cathedral]], also known as the Dome Church (), and the[Russian Orthodox [[Alexander Nevsky Cathedral, Tallinn|Alexander Nevsky Cathedral]].
