The XXVth Anniversary of CercleS brings back memories not only of the CercleS Association and its development, but also of the role of Language Centres in European universities. This article presents the Centre of Languages and Communication (CLC) at Poznan University of Technology (PUT) in Poland. It focuses on the main challenges the CLC has experienced over the years and presents facts from its historical development. It is a very personal article which can be read in two ways: firstly, as a memoir with facts and detailed information about the development of the CLC, and secondly, as a guide for new Language Centres and their managers, who may wish to play a positive role at national and international levels.

语言中心的发展。从历史角度看最佳实践的一个例子

CercleS二十周年纪念不仅带回了CercleS协会及其发展的回忆，而且还带回了欧洲大学语言中心的作用。本文介绍了波兰波兹南工业大学（PUT）的语言和交流中心（CLC）。它着重介绍了CLC多年来经历的主要挑战，并介绍了其历史发展中的事实。这是一篇非常个人的文章，可以通过两种方式阅读：首先，作为回忆录，其中包含有关CLC发展的事实和详细信息；其次，作为新语言中心及其管理人员的指南，他们可能希望参与其中在国家和国际各级发挥积极作用。
