The first record of Suitia (Svidja) is from the year 1420. First known owner was Björn Ragvaldsson, the judge in the Raasepori. After him Fleming family started to use Suitia as their secondary residence. The third owner, Erik Fleming was a remarkable Councilor of State of Sweden. He fought succesfully against Danish army and drove them away from Finland in 1523. After the war Erik Fleming lived in Suitia and extended lands and improved the manor. The present grey stone manor was completed by him about 1550.
Flemings lived in Suitia near 250 years. Their era ended up in 1730, when the Russians had demolished Suitia badly in the Great Northern War. Since it has been owned by several families. It was restored to the late medieval outfit in the beginning of the 20th century by August Wrede af Elimä.
Only battle in Suitia was fought in 1918, when the unit of white army defended it against red guards. The government of Finland reclaimed Suitia in 1934. Nowadays it’s rent to Helsinki University.
The Temple of Portunus or Temple of Fortuna Virilis ('manly fortune') is one of the best preserved of all Roman temples. Its dedication remains unclear, as ancient sources mention several temples in this area of Rome, without saying enough to make it clear which this is.
The temple was originally built in the third or fourth century BC but was rebuilt between 120-80 BC, the rectangular building consists of a tetrastyle portico and cella, raised on a high podium reached by a flight of steps, which it retains.
The temple owes its state of preservation to its being converted for use as a church in 872 and rededicated to Santa Maria Egyziaca (Saint Mary of Egypt). Its Ionic order has been much admired, drawn and engraved and copied since the 16th century. The original coating of stucco over its tufa and travertine construction has been lost.
