The construction of the New Castle at the "Diespecker Tor" (near the later Gasthaus zum (golden) Engel in Bambergerstraße 20, from where a great fire erupted in 1632[2]: p. 334) on the site of the outer bailey of the old moated castle was commissioned in 1575 under Margrave Georg Friedrich (a great-grandson of Albrecht Achilles[2]: p. 91, who was also responsible for a reorganization in the Neustadt area). The master builder and probably the last master mason to execute (the plans completed before 1575) was Peter Fahrenschon, who was married to a woman from Neustadt and came from Meßkirch in Württemberg, presumably with the influence of Thomas Martinotus. Fahrenschon did not receive a fee because the Margrave was dissatisfied with his master builder and even threatened him with death, so that Fahrenschon fled Neustadt to his Swabian homeland. Under Margrave Georg Friedrich (died in April 1603), construction had progressed so far that the wedding of a Baron von Seckendorff (a godchild of the Margrave) was held there as early as 1600. The new building was only completed in 1626 under Margrave Christian, the Margrave of the Principality of Bayreuth.[2]:S. 43, 221-224 With its ground plan solution, it represented an important stage in the history of the development of German castle construction. As a residential castle without actual fortifications, which even used part of the city wall as a house wall, it was one of the first residential complexes of this type in Europe. [2]: p. 43, 221 and 229 The "princely palace" was a stately three-storey building of eleven or fourteen with the tower by four axes. The ground floor opened with ten basket arches on pillars. The octagonal stair tower (with equestrian staircase[56]) stood in the middle of the facade on a sloping base with a round-arched entrance. He wore a slate-domed bonnet with a lantern and knob. A 1610 still existing stepped gable (of originally two) is no longer available. The building withstood an attempted arson attack by a Forchheim garrison that had invaded in 1634. In the 17th century opposite the New Palace were the house of the superintendent and the houses of the deacon (the diaconate or archdeaconate was established in 1570 with the deacon's apartment opposite the chancel of the town church
