The Gates of Dawn, in Vinius, are in fact a single gate tower - the only one of the original nine in the town wall that's still intact. This was once the start of the Moscow road. There is a little 18th century chapel directly over the gate arch which houses a supposedly miracle-working icon of the Virgin, reputed to have been souvenired from the Crimea by Grand Duke Algirdas in 1363, though more probably dating from the 16th century. It is particularly revered by the Polish community, to whom the chapel is known as Ostrabramska.
