=== Monastic State of the Teutonic Knights ===
The settlement was re-fortified again from 1234 by the [[Teutonic Order]]. The erection of the castle, with the help of stone as building material, was begun around the middle of the 13th century. Under the protection of the castle the settlement gradually began to develop into a town.

In 1277 both "the castle and the town" were besieged heavily by the [[Yotvingians]].{{citation needed|date=April 2013}} The settlement adopted [[Kulm law]] in 1291 while under the rule of the [[monastic state of the Teutonic Knights]].<ref name="britannica">{{cite web |url=https://www.britannica.com/EBchecked/topic/247334/Grudziadz |publisher=Encyclopædia Britannica Online |title=Grudziądz |access-date=8 May 2013 |archive-date=22 March 2014 |archive-url=https://web.archive.org/web/20140322071451/https://www.britannica.com/EBchecked/topic/247334/Grudziadz |url-status=live }}</ref>

The oldest building parts of the Catholic St. Nicholas' Church stem from the end of the 13th century. The Holy Spirit Church, which apparently was founded during the 13th century, is mentioned together with the town's hospital for the first time in 1345.{{citation needed|date=April 2013}} Other documents reveal that in the 14th century the town already had a well-developed infrastructure. A document of 1380, as an example, refers to the construction of an aqueduct, a fountain and a town-hall cellar.{{citation needed|date=April 2013}}

In the 14th century, papal verdicts ordered the restoration of the town and region to Poland, however, the Teutonic Knights did not comply and continued to occupy it.<ref>{{cite web|url=https://encyklopedia.pwn.pl/haslo/wojny-polsko-krzyzackie;3997560.html|title=wojny polsko-krzyżackie|website=Encyklopedia PWN|access-date=19 April 2024|language=pl}}</ref> During the era of the Teutonic Knights, Graudenz had become a distinguished trade center in particular for textiles and agricultural products including grain.{{citation needed|date=May 2013}} Around 1454, Graudenz had already reached about the same level of economic development as other towns in the western part of the [[State of the Teutonic Order]], such as [[Danzig]] (''Gdańsk''), [[Elbląg|Elbing]] (''Elbląg''), [[Toruń|Thorn]] (''Toruń''), [[Malbork|Marienburg]] (''Malbork''), [[Chełmno|Kulm]] (''Chełmno''), [[Chojnice|Konitz]] (''Chojnice''), [[Nowe Miasto Lubawskie|Neumark]] (''Nowe Miasto Lubawskie'') and [[Starogard Gdański|Preußisch Stargard]] (''Starogard Gdański'').{{citation needed|date=April 2013}}
