A word CUP isn't related to any sport at all, but it stands for Centrinė Universalinė Parduotuvė (Central Department Store).
This shopping mall and Hotel Radisson Blu Lietuva (tall building on the right side) were built in 1970s as the beginning of Vilnius city expansion to the Neris river right coast.
Thanks to Justas for providing this great photo :)
