Havis Amanda is a nude female statue sculpted by Ville Vallgren (1855-1940). He made it 1906 in Paris, but was not erected at its present location at the Market Square in Kaartinkaupunki until 1908. Havis Amanda is one of Vallgren's Parisian Art Nouveau works. She is a mermaid who stands on seaweed as she rises from the water, with four fish spouting water at her feet and surrounded by four sea lions. She is depicted leaning backwards as if to say goodbye to her element. Vallgren's intention was to symbolize the rebirth of Helsinki. The height of the statue is 194 centimetres and with the pedestal it stands 5 metres tall. According to Vallgren's letters the model for the statue was a then 19-year-old Parisian lady, Marcelle Delquini.
Havis Amanda is the most popular statue in Helsinki. Every year on 30th of April it serves as a centrepiece for the celebrations. Students of the local universities put a cap on the statue on an elaborate ceremony.
The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
