The celebration on Öland takes place for several days in connection with Crown Princess Victoria's birthday on 14 July.
New for this year is a procession that will go from Solliden to Borgholm's castle ruins.
One of the highlights of the Victoria Days is the awarding of the Victoria Prize.
21-year-old Ebba Årsjö, born in Oskarshamn, is this year's winner.
She took two gold and one bronze at the Paralympics in Beijing.
This is the first time a parade athlete has been awarded the award.
- I was very honored when they called.
I checked the list (with winners) on Wikipedia.
I do not know if you have seen the list?
It is quite massive, Ebba Öberg told SVT Sport earlier.
Tomas Ledin, Tove Styrke, Janice, Victor Leksell and Jonathan Johansson will perform at tonight's concert.
The award ceremony and the Victoria concert will be broadcast at 21:00 on SVT1 and SVT play on 14 July.
