8. LINNAKAUPUNKI (”CASTLETOWN”) PARTIAL MASTER PLAN, 25.2.2012
The Castletown area will be developed to supplement the urban structure of the City.
The land use of old, unefficiently used industrial and harbour areas – so-called brownfields - shall be renewed and the efficiency increased.
The overall diffuse appearance of the built surroundings will be enhanced and transformed in an urban environment.
The medieval Castle and its surroundings will be highlighted as a historical site of international attractivity.
The touristic functions of the ferry harbour shall be linked to the activities of the Castletown area.
The implementation of the plan is scheduled for approximately 2030 – 2035.
Castletown will be developed as a district for pedestrians and cycling.
Sustainability shall be adapted in all detail projects on the Castletown area, in all its respects, ecological, economical and social.
