Like I said. there are no "studylodges" in the Netherlands. There is a "Stichting Ritus en Tempelbouw" ('rite and temple construction foundation' would be the literal translation (quick Google translation from their
website:
The Foundation Rite Temple and Construction, founded on June 2, 1946 in which two clubs merging that had to cease their activities during the war, viz .:
Mac. union to study of symbols and rituals, founded in May 1905 and Foundation Temple Building, which originated in 1931 and who was interested in the design of lodge rooms, furniture, regalia and eg. the Tableau.
The Foundation is an independent, she does not represent a certain current within Freemasonry nor any Order and works in the Dutch language.
She aims her activities, including first and foremost the journal Thoth, research and study to promote the field of Freemasonry and to indicate their results widely publicized.
Justification of our doings is made to the Advisory Council, which is composed of a number of participants of R & T. The Foundation and Rite Temple Construction has over the years published a number of very interesting fixed standard works, which for the freemason as basic or study funds.
Because the legal form of a foundation, it has no members, but participants or contributors and the Assembly that a foundation does not know replaced by exchange with the participants or contributors thoughts at the annual National Workshop.
Freemason who are interested in the (study) Freemasonry can participant or contributor to the Foundation 'Rite Temple and building'. Contributors six times a year the magazine Thoth and -at publication- other publications free of charge or at reduced prices.
They may also, against payment, to participate in the Foundation organized seminars."
The foundation has seminars, lectures, studygroups, etc. Perhaps there are also "Masonic meetings" only for Grand Orient members, I don't know. In any case, as an irregular Mason I am member myself. I receive their journal, can go to seminars, but not to FC or MM themed meetings since they do check my degree at my order. The next upcoming event is a "day of meeting" organised together with a similar organisation from Belgium and on that day they hope to get Masons from any kind together to meet.
Now in Belgium there
are "studylodges" in the meaning I think the original poster is thinking of.
The difference between countries eh?
