Middelalderparken, the Medieval Park, lies in Gamlebyen, the part of Oslo that was actually called Oslo before King Christian IV moved the city and renamed it Christiania in 1624. When the city got its old name back in 1925, this original settlement was renamed Gamlebyen, the Old Town. Which means there is an Oslogate, Oslo Street, in Oslo, and the reason is that it used to be in the other Oslo.
Do not expect anything like the medieval old towns of Prague or Tallinn. Almost nothing of the original medieval city survives above ground. What you will find are the excavated ruins of several churches and the old Royal Manor of Oslo, Oslo Ladegård. The most significant ruin is the Mariakirken, St. Mary's Church, which was the city's main church in the Middle Ages. Nearby are the remains of Olavsklosteret, a Dominican monastery, and Korskirken, the Church of the Cross.
The ruins are modest, but the park gives a sense of scale for how small medieval Oslo really was. During summer, there are guided tours organised through Oslo Ladegård that bring the history to life; check their website for dates. The park itself is open year-round and free to enter. It is an easy walk from Oslo S, heading east along Bispegata.
