チェルモス–ヴライコス国立公園の天然記念物・トップ4

アギオス・ニコラオス・グルナ地方と隣接するヴライコス渓谷の岩壁は、地質学的に非常に特徴的です。 ここの岩石は主に2つのタイプで構成されています。 赤い礫岩：これらは特に顕著で、多くの岩壁に特徴的な粗い構造と赤みを帯びた色を与えています。礫岩は、細かい基質によって「接合」された丸みを帯びた岩石の破片（小石など）で構成される堆積岩です。 石灰岩：この地域が属するチェルモス・ヴライコスユネスコ世界ジオパークの大部分は、石灰岩で構成されています。これはしばしば強くカルスト化されており、渓谷の多くの洞窟や印象的な岩石層の形成に貢献しています。

The name "Orias" derives from the legend of Aikaterini Paleologou, who threw herself from the castle to her death in 1463 to escape capture by the Turks. The site is a popular destination for hikers. A moderate circular trail leads from the Kalavryta Massacre Memorial up to the castle hill.

Castle Rock of Kalavryta is known locally as Kastro of Orias (Castle of the Beautiful Lady). It is situated at an altitude of approximately 1,100 to 1,170 meters. The medieval fortress was originally built in 1208 by the Frankish de Tournay family. In March 1821, the first cannon was fired from this castle, marking the beginning of the Greek Revolution against the Ottoman Empire. Today, mostly ruins remain, including remnants of walls, water tanks, and two semicircular towers.
