Ryszard Markwart, or Richard Marquardt (1868-1906) was a German-Polish catholic priest and Polish national activist who served in Magdeburg, Berlin and Bydgoszcz.

To replace him, Florian Stablewski, the serving archbishop of Gniezno, supported Markwart candidacy for the position of parson of the only catholic parish of Bromberg.

Like his predecessor Józef Choraszewski, Father Markwart faced constant challenges to provide pastoral care in his vast and populous parish.

The project designed by architect Roger Sławski will be eventually carried out in autumn 1912: the Church of the Holy Trinity was consecrated on 18 May 1913 by Gniezno suffragan bishop Wilhelm Kloske.

[6] Feeling deep attachments to his mother Polish roots he had changed his birth name Richard Marquardt to Ryszard Markwart.

They informed the institutions of the Bromberg region, claiming falsely that Father Markwart defied the law by teaching religion lessons in Polish.

In parallel, German Catholics in Bromberg, having been denied by Ryszard the possibility to create a separate parish church, asked for his departure from the city in 1904.
