Considering the Campanile - Leeuwarden in Leeuwarden?

Jacobijnerkerk or Great Church by OlafS
This biggest protestant church of Leeuwarden belonged to a Jacobin monastery until the protestants confiscated it. Typical for such a monastic church is the lack of a tower, which makes the church a bit difficult to find at first. The choir is a mausoleum for the Frisian branch of the (Oranje-)Nassau family, the ancestors of the current royal family.
