Masonic Lodge St. Johannisloge "Zum Widder" in Potsdam

Welcome to the website of the Masonic Lodge St. Johannisloge "Zum Widder" in Potsdam. As a brotherhood that is now more than 244 years old, we are one of the oldest Masonic lodges in the greater Berlin/Brandenburg area with more than 70 brothers and an average age of less than 50 years.

What is Freemasonry?

Freemasonry is a certain way of life of an individual in relation to his fellow human beings. This way of life is characterized by ethical principles, honorability, tolerance, charity and religiosity. The rituals of the Freemasons, their symbolic language, but above all their basic spiritual attitude, are essentially due to the medieval cathedral huts.

Origins of Freemasonry

The origins of Masonic ideas can be traced back to antiquity. Approaches to these ideas can be found from the Gilgamesh epic about the cultures of ancient Egypt, Plato in the Hellenistic world, to the Middle Ages of the Knights Templar.

Do not hesitate to contact us personally at any time via the contact form.

We meet regularly for social events, lecture evenings and loge rides as well as – and this is the core of our community – for the masonry work on the "Rauhen Stein", as we call Freemasons.

For the brother Freemason as well as the interested guest we would like to give an overview of Freemasonry in general and of course in particular to our Potsdam St. Johannisloge.

Interested gentlemen and guests of our Masonic Lodge

Dear friends of our Johannisloge and interested gentlemen and guests, we offer an evening once a month for seekers. The term seeker is the Masonic term for future brothers.

The guest evening of our lodge usually takes place in the Order House Berlin. Here every guest has the opportunity to listen to lectures on current as well as historical topics related to Freemasonry and to learn more about the ideas of our brotherhood in a personal conversation with Freemasons. Of course, every guest has the opportunity to ask questions about Freemasonry in general and our lodge in particular.


Our lodge belongs to the Great Land Lodge of the Freemasons of Germany (Freemason order), one of the five grand lodges in which the German Freemasons are organized. We meet at our guest evenings in the lodge of the Großer National – Mother Lodge "Zu den drei Weltkugeln" at Heerstrasse 28 in 14052 Berlin-Charlottenburg. The Order House, the seat of the GLLFvD in Berlin, at Peter-Lenné-Straße 1-3 is currently being rebuilt.
