This museum is an amalgamation of smaller museums scattered all over the city. Along with the free entry, what these museums have in common is the fact that they focus on one aspect of the past or present of the city. The main museum just off Senaatintori is the most sought-after one among the museums. The impressive collection of artefacts and photos depict accurately the colourful past of Helsinki, its transition from Swedish hands to Russian and now where it stands at present.
