All Saints' Abbey (Kloster Allerheiligen) was a Premonstratensian monastery founded around 1192 when a wooden chapel was built, which was gradually extended to be a monastery. In 1196 the foundation charter was issued by Duchess Uta of Schauenburg. In 1200 Philip of Swabia recognised the foundation, and in 1204 Pope Innocent III confirmed it. The first abbot was Gerung.
In 1248 canons from All Saints were sent to Lorsch Abbey to turn it into a Premonstratensian monastery, since when Lorsch was counted as a daughter house of All Saints. Another daughter house was set up at Haguenau. Through various gifts and livings, inter alia at Oberkirch and Oppenau, the monastery grew rapidly and became one of the major religious, cultural and political centres of the region.
In 1657 it was raised to the status of 'abbey' by the general chapter of the Premonstratensian Order. In the 18th century it was at the high point of its power. In November 1802 however Margrave Karl Friedrich of Baden dissolved the abbey in the course of secularisation, and took all its possessions.
Large fires, in 1470 and 1555, had already destroyed parts of the premises. In 1804, a last fire, started when a bolt of lightning struck the church tower, finished the job. In 1816 the ruins were sold for demolition and used as a quarry for stone and scrap for churches in the valleys of the Rench and the Acher. The altars and saints' figures are to be found in numerous local churches, for example in Bad Peterstal, Oppenau, Ottenhöfen and Achern. Three statues from All Saints' Abbey are above the gateway of the prince's chapel at Lichtenthal Abbey, representing Saint Helena, Uta of Schauenburg and Gerung.
Not until the end of the 19th century, when tourism finally reached the Lierbach valley and its waterfalls, were any steps taken to secure what was left of the ruins, which were then put into the condition they are in today.
On a rise above the ruins of the monastery complex is a war memorial for the fallen and deceased members of the Black Forest Society (Schwarzwaldverein), raised in 1925 by C.M. Meckel und A. Rickert.
In 1947 the Charitable Union of Mainz acquired the area round about the monastery ruins and built a convalescent home for children there. Since 1978 this has been used as a country holiday centre for schools. In 1960 the Bishop of Mainz built a chapel here that, like the abbey church, is dedicated to the honour of God and All Saints.
Also now on the site are a cafe and a small museum. Below the ruins are the All Saints' Waterfalls ('Allerheiligen-Wasserfälle').
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.
