Lodge Willem Fredrik initiates a maximum of five new members per year. We invite free men of good standing, from all walks of life, colourful and of any creed, to contact us if they are curious.

Our lodge meets twice per month, currently on the first Monday and fourth Friday of the month. The Friday evenings are usually reserved for more festive masonic occasions.

Twice per year we organize a public lecture, where anyone who is interested is most welcome. An informal meeting, which allows for a more personal acquaintance and in depth conversation,  with one or more of our members is always possible as well.

You haven’t found any specific names of our members on this website. This isn’t because we do not wish to be open or transparent, but because we value our and your privacy in a time where everything is considered to have to be public information and digitally accessible.

Open gatherings

Lodge Willem Fredrik organises open gatherings throughout the year with guest-speakers. The lodge, regardless of it’s private nature, attaches value to being part of this world . By inviting speakers that address important social issues and developments and at the same time involve friends and those who are interested. In the conversation after the lecture, we strive to follow the free mason’s method: dialogue instead of discussion and debate, in which we listen well and respect one another’s points of view, even if we do not agree. This leaves intact the possibility to adjust one’s opinion under the influence of others.
