Waà Âcz (; ) is a county town in Waà Âcz County of the West Pomeranian Voivodeship in northwestern Poland.
Granted city rights in 1303, Waà Âcz has become the administrative, industrial and cultural center of the Waà Âcz Lake District with the city itself situated on the banks of the Raduà  and Zamkowe lakes. Waà Âcz is located in the southestern portion of West Pomeranian Voivodeship. The closest cities are Szczecin , Bydgoszcz , Pià Âa , Poznaà  , Gorzów Wielkopolski and Koszalin .
Historically, the town belonged to the province of Greater Poland and was a royal city of Poland until the Partitions of Poland. Afterwards, from 1772 to 1945 it was part of Prussia and, from 1871 to 1945, it was also part of Germany, before being reintegrated with Poland. It is the location of one of the oldest high schools in Poland, founded over 350 years ago, and a garrison of the Polish Army.
According to a report from 2002, Waà Âcz has an area of of which 41% is used for agriculture and 17% is forest.
There are two large lakes within the town limits: Raduà  (area - , length - , shoreline - over , maximum depth - , average depth - ) and Zamkowe (area - , length - , shoreline - over , maximum depth - , average depth - ). There are also four smaller lakes within the town limits: Cegielnia, Chmiel Duà ¼y, Chmiel Maà Ây, Raduà  Maà Ây, and several more within a short distance of Waà Âcz, including Ostrowiec Wielki, à Âubianka, à ÂabÃÂdzie. Lake Raduà  is spanned by the Kà Âosowski suspension bridge.
The town occupies 2.17% of the total area of Waà Âcz county.
In the High Middle Ages the region of modern Waà Âcz was a boundary territory between Pomerania and Greater Poland. It was included within the emerging Polish state in the late 10th century, and was integrated into the Kingdom of Poland again in the early 12th century. Later, as a result of the fragmentation of Poland, it became part of the Duchy of Greater Poland. Except for a brief period of Brandenburg rule (in the 14th century), it remained part of Poland until the first partition in 1772. After the town was recovered by King Casimir III the Great in 1368, it was a royal town and county seat, administratively located in the Poznaà  Voivodeship of the Greater Poland Province. In 1618 Jan Gostomski, starost of Waà Âcz, brought the Jesuits to the town, who founded the Jesuit College, nicknamed the "Waà Âcz Athens", in the 1660s, which as today's I Liceum Ogólnoksztaà Âcàce im. Kazimierza Wielkiego, is one of the oldest high schools in northwestern Poland.
During Prussian and German rule, Waà Âcz was known by the newly given name Deutsch Krone. It was initially part of the Netze District, which while formally separate was ruled from the province of West Prussia after 1775; it formally became part of West Prussia following the 1807 Treaties of Tilsit which partitioned the Netze District. In 1781, the Jesuit College was transformed into a Royal Gymnasium, whose director was Józef Dalski. Lessons in Polish were held until 1831, when the school, similar to the town, was subjected to Germanisation. However, its director from 1866 to 1890 was a Pole, Antoni à Âowià Âski. At that time, Polish lessons were restored as an optional, additional course for students, and a secret Polish youth philomath organization Ul operated in the school. à Âowià Âski's gravestone at the local cemetery is the only one facing away from the main cemetery alley, because the German administration opposed using Latin inscriptions, instead of German. In 1831âÂÂ1832, one of the main escape routes for insurgents of the Polish November Uprising from partitioned Poland to the Great Emigration led through the town.
After the First World War it was one of the few towns of historical Greater Poland that were not included in the borders of Poland after regaining independence in 1918. Deutsch Krone, having a predominantly German population, remained part of Weimar Germany and was part of the Posen-West Prussia province until 1938 when it was assigned to Pomerania. During World War II, the German administration operated a labor camp for French and American prisoners of war from the Stalag II-B prisoner-of-war camp in the town. The Polish resistance conducted espionage of German activity in the town. The town was occupied by the Red Army on 12 February 1945. After the end of World War II, the town became again part of Poland according to the Potsdam Conference and renamed to its historic name Waà Âcz. Also in accordance to the Potsdam Agreement, its German inhabitants were expropriated and expelled. The town was repopulated by Poles, most of whom were themselves expelled from the former eastern territories of Poland annexed by the Soviet Union.
Numerous pre-war ruins of German fortifications and bunkers are found in woods surrounding Waà Âcz, especially in proximity to the lakes. Most of them however are inaccessible â blown up or filled with soil, to prevent accidents with careless tourists.
From 1975 to 1998, the town was administratively part of the Pià Âa Voivodeship.
The lack of heavy industry in Waà Âcz and the surrounding areas has helped the city to maintain relative ecological cleanliness and is an excellent location for rest and relaxation. It has a post office that was built during the reign of Napoleon.
Next to the suspension bridge on Lake Raduà  in a beechwood forest is an Olympic Training Facility, the 'Bukowina'. Immediately after World War II, Winand Osià Âski and Olympic coach Jan Mulak founded the training centre and began training with the Polish track and field teams who represented Poland during the 50s and 60s. Poland's Olympic kayak team trains here to this day.
On this lake is also the City Centre for Sport and Recreation (MOSiR - Miejski Oà Ârodek Sportu i Rekreacji) which makes a wide range of sporting equipment available, including motor boats, kayaks, water bikes and the leisure boat Delfin. The centre also serves as a starting point for numerous walking and biking trails as well as kayak excursions. The so-called PÃÂtla Waà Âecka, a kayaking route that traverses six lakes begins here and ends at Lake Bytyà  Wielki.
Situated on the shores of the lakes are numerous beaches, swimming areas, camping spots and sporting equipment rentals.
