Seda is a town in the Valka district of Latvia, with 1,500 inhabitants. It lies just 20 km from Valka and Estonian border. It's an industrial town built in 1953 for the workers of Seda peat marshes located nearby. The inhabitants were brought here from all over the Soviet Union.
Seda is so small that the best way to get around is by foot.
Seda itself is a monument of Stalinist architecture. It's a perfect place for people seeking Soviet nostalgia.
Walk around those 3 streets - it will not take more than an hour. Or, take a trip on a narrow-gauge train going to the peat marshes.
