Maria Rickenbach Monastery was initially established after a 1528 painting of the Blessed Mother was placed in a hollow maple tree on that site. Subsequently, unable to remove the painting, which came to be considered miraculous, the church and monastery were established around the tree, which is now enclosed by a shrine.
In 1857, a small group of women who wanted to follow a monastic way of life acquired the monastery. There they established the practice of Perpetual Adoration as a part of their life. The monastery is often associated with Engelberg Abbey, under the guidance of which they were established and later became formally incorporated into the Benedictine Order.
It is accessible to the public only by cable car from Niederrickenbach Station on the Luzern–Stans–Engelberg railway line.
References:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
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.
