Haras de Braniewo, Horse stud farm and monument in Braniewo, Poland

The Haras de Braniewo is a historic stud farm complex on the outskirts of Braniewo, at today's ulica Moniuszki. Built in 1889–1891 in the functionalist style of late 19th-century Prussian architecture, it has dark red brick walls and includes a main stable, a second stable, a riding hall, a forge, a trainer's house, a director's villa and a park with training grounds. The complex was listed as a monument in 2007 under A-4467.

The Königliches Landesgestüt complex was built in 1889–1891 on the outskirts of Braniewo at Rodelshöfer Straße, now Moniuszki Street, and began operating in 1890, breeding mainly Trakehner and Sztum horses. Thirteen managers led it until 1945. In January 1945 the last manager, Hermann-Wilhelm von Warburg, drove part of the herd across the frozen Vistula Lagoon; on 3 February 1945 Dr Ernst Arnold followed with 103 Trakehner stallions and 11 draft horses to Redefin. A transit camp for Germans occupied the site in 1945, and a state stallion herd was re-established in 1951, listed as a monument in 2007.

The name Braniewo comes from the Prussian settlement of Brunsberg; the stud farm itself was called Königliches Landesgestüt. In 1951 the first inter-farm equestrian competition in the voivodeship was held here, with a carriage-driving display, on a football pitch adapted as a hippodrome. The best horses bred here in the 1950s were Baronet and Monopol.

The complex stands on the northern edge of Braniewo at ul. Moniuszki, about a kilometre from the centre, so it is reached on foot or by car rather than from open countryside. The former director's villa now houses the Municipal Sports Centre "Zatoka". A 2021 redevelopment added paths, a car park, benches, bike racks and an outdoor gym.

The stud farm's main stable, indoor riding hall and much of the director's villa interior survived both world wars largely intact. Since 2007 the complex has been listed as monument A-4467, and the former director's villa now houses the offices of the Municipal Sports Centre "Zatoka".
