Seapoint

One of the better kept secrets of Helsinki is the beach on Uunisaari, an island a short ride away from the south coast.

A prime example of 1930s functionalism at the border of districts of Eira and Punavuori. Slightly unusually for this architectural style it's constructed in red bricks. The spire of the church can be lowered into the church tower, a feature that was used during WWII to make it less visible for Soviet bombers.

The 1926 yellow-coloured observatory, operated by the Astronomical Association Ursa, is still in active use by both members and other enthusiasts, but non-members can also attend public shows to either observe solar phenomena or look at the starry sky.

A beautiful park by the sea in the namesake neighbourhood in the southernmost part of the city. In summer you might want to sit down for a cup of coffee in one of the seaside cafes and enjoy the view of sailboats and the people on the promenade. Housing surrounding this area is the most expensive in Helsinki.

The largest church in Helsinki and a fine example of Gothic Revival architecture.

As the name reveals, this hill rising above the Olympia and Makasiini terminals of South Harbor hosts an observatory, and from the hill you have a nice albeit partial view over the city centre (part of the view is obstructed by trees). It is also the place for people to picnic on the may day festival Vappu and on the morning of the Finnish Independence Day the hill hosts a televised flag rising ceremony.
