Construction of the first church in Lemi was started in 1668, but it was destroyed by arson already in 1670. The next one was completed in 1688 and used for one hundred years. The present one was built in 1786 by the local church builder Juhana Salonen. The wooden crusiform-shaped church is one of the most valuable wooden churches in the Europe.
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.
