The support rally happened by the monument to Rainis, a famous poet who had fled Latvia in times of turmoil, and some held posters saying "Rainis was a refugee too".
The majority of the participants were young people. Several people who object to immigration also had arrived, wearing T-shirts, saying "Stop immigration".
The goal of the picket was to support Europe's Action Day "Europe Says Welcome" and to show solidarity with refugees.
The Latvian government agreed earlier to voluntarily accept 250 refugees, but, in line with the new EU refugee relocation scheme presented by Juncker on September 9, Latvia might have to admit additional 526 refugees.
The coalition is divided on this matter, and President Raimonds Vējonis will visit the ruling parties to try mollifying their stance.
