It is not a favourite city of mine I have to say, it is pretty busy, haotic and dirty. However in the city center there is a lot of pretty and colourful architecture in Western style with local interpretations of Neo-Renaissance, Neo-Baroque, Neoclassicism, Art Nouveau and Art Deco.
Unfortunately almost all of the beautiful buildings in the center got additionally "decorated" with huge advertisements, which i find pretty grotesk and ugly...The sea garden along the beach is the oldest and biggest park of the city.
Varna is a front-runner for European Capital of Culture for 2019, planning to open several new high-profile facilities such as a new opera house and concert hall, a new exhibition centre, and a reconstruction of the Summer Theatre, the historic venue of the International Ballet Competition.
And something with which Varna beats even Sofia....is of course the sea:-) And last but not least Varna offers a great attraction with the its dolphinarium!
