Alexander Nevsky Cathedral Tallinn, Tallinn

Alexander Nevsky Cathedral Tallinn, Tallinn (Estonia)

The spectacular onion-domed shaped structure is one of the grandest Orthodox Church in Tallinn. It’s designed in a different historical style perched atop on Toompea hill in 1900. Within the tower of the church is the most powerful collection of church bells. There are about 11 bells in there, including its largest bell which weighs about 15 tonnes. Before each service starts, you can hear the whole ensemble playing so in tune. As for its interiors, it’s so beautifully adorned and decorated with icons and mosaic; it’s such an attraction that’s worth to visit.
