A late nineteenth-century fire station building in the Gamlebyen district east of central Oslo, among the surviving examples of public architecture from that period. The building is red brick with a tall watchtower — and that tower was the original function: before telephones, a watchman stood at the top to spot smoke across the city and ring the bell. Oslo was largely a timber city and had burned repeatedly, so spotting fires was a question of survival. The building today is in other use and is not visited inside. What you do is look at it from the street, and that takes a few minutes. Its value is that it stands in Gamlebyen, the district Oslo began in: this was the medieval city before a great fire in the seventeenth century destroyed it and the city was moved west. Stone remains of the old town are still visible in a nearby park. This is a residential district off the visitor route, another face of Oslo beyond the waterfront and the museums. Free and seen at any time.

Oslo was largely timber and burned repeatedly — fire-spotting was survival.
Stone ruins of old Oslo are visible in a nearby park.

After a fire in 1624 King Christian IV ordered the city moved west beneath the walls of Akershus fortress and named it Christiania. The ruins of the original city — stone churches and monasteries — survive and are visible today in an open archaeological park.
For anyone staying in Oslo more than two days or interested in the city's history, yes: the archaeological ruins are free and open and explain Oslo's origin. On a short visit, the waterfront, the Bygdøy museums, the Vigeland park and the Munch museum have a far better claim.
