St. Paraskevi Church in Radruż dates from the sixteenth-century, which together with different tserkvas is designated as part of the UNESCO Wooden tserkvas of the Carpathian region in Poland and Ukraine.
The tserkva belongs to the oldest and best kept wooden sacramental architecture tserkvas in Poland. Part of the prestigious World Monuments Fund (WMF) list of buildings worthy of preservation and financial sponsorship.
The tserkva is located on an oval hill, by the Radrużka stream, and together with the bell tower is surrounded by a wall (existent from 1825), with a fortification structure. The tserkva's structure is constructed out of a fir and oak framework. The tserkva was most likely funded by poseł to Sejm, and starosta Jan Płaza (died 1599). While being used for sacramental services, the tserkva was also used as a fortress against the invasions by the Tatars.

The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
