was held on August 30 – September 4, 1966 in Prague, Czech Republic. It was organized by the Czechoslovak Academy of Sciences in cooperation with the Association of Czechoslovak Mathematicians and Physicists.
The Symposium was attended by 131 participants from 16 countries, including 41 from Czechoslovakia. The scientific programme consisted of 11 invited addresses in plenary sessions and 78 contributed papers into parallel sessions.
Most of the invited addresses and contributed papers, including a few papers presented in writing only, were published in General Topology and its Relations to Modern Analysis and Algebra II, Proceedings of the Second Prague Topological Symposium 1966 (Academia Prague, 1967).
