The source is situated at the gateway to Saxon Switzerland and the Elbe Sandstone Mountains – just above a romantic little town. Here, in an idyllic park in the Sonnenstein Castle grounds, the water is collected from the Sonnenstein® spring.

The primary water comes directly from the crystalline bedrock of Saxon Switzerland, on the edge of the Eastern Ore Mountains. Protected approx. 80 metres underground, it has no connection to the surface of the earth and is naturally mineralised on its way to the spring.

Sonnenstein® mineral water is primary water, which means it has never come into contact with the earth’s surface and its water cycle. It is completely free of any harmful substances and is filled into bottles under its own pressure, without it being adversely affected by strong electromagnetic fields – essentially by hand.


Special, naturally pure primary water rises from the Sonnenstein® spring.

The castle and the spring both lie directly on a ley line. There are a number of extraordinary historic locations along this line. There are many theories about ley lines.


The primary water is carefully collected and bottled under its own pressure so that its natural characteristics and crystalline structure are retained. This is made possible by the gentle, meandering route of the fully welded, stainless steel pipes, with no kinks or bolted connections – from the spring to the bottling station.

The manufactory and bottling station are just 40m distance from the spring.

Sonnenstein® water was first documented in 1468. From the Erlpeterbrunnen (Alder Peter’s fountain), flowed finest spring water that, according to legend, was very special. Above the fountain, where the water flowed from a stone bottle, stood a poem:

My name is Alder Peter,
Poor folk know me well
Those who have no money,
Can drink with me from my bottle

According to Wendler’s town chronicle, the name comes from the Junker, Peter, who secretly met with the daughter of a knight from Sonnenstein under the alder tree (German: Erle) at the foot of the castle hill. When the Junker died, she mourned at the foot of the alder tree. On the anniversary of his death, his ghost appeared and spirited her away. The legend was recorded in the following poem:

They were spirited away
Those two who drank the dewy tears
A spring sprang from the rocks
Refreshing and sparkling silver
Like a holy miracle worker
It became known far and wide
And it is still known as Alder Peter
To this very day

The Erlpeter spring dried up in 1549 and did not reappear – because people apparently “started making money out of the water”.

It was later tapped again at enormous cost, but was destroyed during the Thirty Years’ War. (There has been an Erlpeterbrunnen below Sonnenstein Castle since 1907. However, it no longer has the same high quality as the original.)

Following the tradition of the fountain, the newly tapped Sonnenstein® mineral water will now be made available to those in need via a fountain – free of charge.


First mentioned in 1100, Sonnenstein was originally a fortress but later used as a castle for the electors. It therefore became known as both a fortress and a castle. Almost nothing remains of the Renaissance buildings. The Thirty Years’ War severely damaged the fortress. On 23 April, 1639, the Swedes captured the City of Pirna; however, the Sonnenstein fortress was spared. Around 1670, after the Thirty Years’ War and as the Baroque style began to take hold in Saxony, the fortress was expanded. Today, only the mighty outer walls remain. In 1810, the complex was again expanded and a psychiatric hospital established in the castle and its extensive grounds.

Medical historian Zeller stated: “The sun of German psychiatry […] rose on the Sonnenstein in Saxony”.

Sonnenstein Historie

The picturesque Sonnenstein fortress situated above the town of Pirna has a history that spans over a thousand years. This complex can look back on a mythological past, because even the Celts utilised this holy place of power.
