The boundary of the village encompasses an area of about, of which about 80% is covered by forest. Approximately 350 people live in the village. The village is situated on the eastern bank of the Eder River. To the east of the village is the Quillerwald or Markwald, the latter so-called because once it belonged to all the surrounding villages, at least in terms of the right to cut wood and graze animals, but not hunting. The Eder River confluences with the Fulda River just upstream from Altenbrunslar at Edermünde.
Geology
The bedrock is composed ofTriassicBuntsandstein. It is so-called because it is composed of different-coloured sandstones. The rolling hills that are caused by the nearly even weathering of the sandstones, are punctuated by steep basaltic outcrops, which are the remains of Neogene volcanic necks.
, found near the town of Rhünda, which is just south of Felsberg, proves that this area was populated already 12000years ago. Archaeological finds show that around c.2900–2450cal. BC, in the nearby Quiller Forest, a prehistoric people of the Corded Ware culture settled. During the building of the A7 motorway in 1935, many burial mounds were found on Schleifsteinskopf, a hill within Quiller Forest. At around the same time, the Riesenstein, a menhir weighing more than, was erected close to Wolfershausen.
The first mention of the place Bruneslar was in 1154. The first recognised use of the name Altenbrunslar was in a document from 1381, in the list of possessions of Friedrich III von Hertingshausen, a knight from the surrounding area. In 1527, after the Protestant Reformation, Johannes Bonecker, a monk from the Breitenau Monastery, applied for the post of vicar in Altenbrunslar. The first protestant vicar installed in the chapel was Ludolphus from 1528 to 1534.
In 1639, the village was named Altenbraunßlar in the hessische Mannschaftsregister. Brunslar has always been an important location for armies to cross the River Eder. For instance, in the Seven Years' War, when in 1760 John Manners, Marquess of Granby lead his troops to confront the French, he bridged the River Eder at Brunslar.
The first section of the Main–Weser Railway between Kassel and Wabern, running directly through Altenbrunslar, was opened on 29 December 1849. The first train to pass through Altenbrunslar was pulled by the HenschellocomotiveHassia The first continuous rail service from Kassel to Frankfurt ran on 15 May 1852, although there wasn't a railway station at Altenbrunslar to start with. After petitioning, a station was constructed in 1902.
20th century
During the Second World War, the Allies bombed and breached the Edersee Dam in the night of 16–17May1943, as part of Operation Chastise. The resultant flood wave hit Altenbrunslar half an hour later. The population of Altenbrunslar fled into the forest after they were warned by radio. The whole Eder Valley and most of the village was flooded, but the bridge mostly stood up to the water and only the upper part was in need of repair afterwards. A number of houses close to the river were damaged.
Administration
From 1413 to 1807 and from 1813 to 1821, Altenbrunslar belonged to the administration of Felsberg, from 1807 to 1813 to the Canton of Gensungen of Napoleon'sKingdom of Westphalia, and from 1821 onwards to the District of Melsungen, which, in 1866, became part of the Kingdom of Prussia. On the 1 February 1971, Altenbrunslar joined Neuenbrunslar to become the Brunslar Community. This was incorporated into the town of Felsberg on 1 January 1974.
Architecture
The first permanent sandstone bridge over the Eder River at Altenbrunslar was built in 1885. Before this bridge, there was only a temporary wooden bridge in summer and a ferryman in winter. The small, evangelical chapel in Altenbrunslar is an object of cultural heritage. It was originally built, probably at the beginning of the 10th century, in the romanesque style, but later a gothic stylechoir was added. Above the aisle is a half-timbered upper level that was constructed in 1681. The upper level was used in the past as a granary. In 2000, the chapel was completely renovated. The church bell is reported to have come from the nearby ruined village of Brechelsdorf. On the bell is written in Gothic script: "im jahr des herren 1487 gegrüßt seist du maria".

Art events
On the weekend of 5–6 September 2015, Alten- and Neunenbrunslar held a bridge party to celebrate the sandstone bridge over the Eder. Otto W. Werren, a local artist, had the idea to weave old fire brigade hoses, which have a bright yellow-green colour, into the posts of the handrails on the side of the bridge. This was carried out by the youth of the villages. For the weekend, the bridge was illuminated with different coloured lights.
Altenbrunslar was chosen as Dolles Dorf in the Hessischer Rundfunk television programme of the same name. A ten-minute film about the village was broadcast on 25 August 2012.
