The name of the village is first mentioned in a charter by Béla IV dated 5 May 1266, as Solomar. The most likely etymology of the name is Hungariansolymár : ‘falconer’, i.e., the place where the royal falconers live. The village prospered during the following centuries and probably hosted a royal hunting castle, which burnt down after 1561. The advance of the Ottoman Empire left the village deserted after 1580. The village was uninhabited until the first new settlers arrived around 1700; first Serbians and Bulgarians migrated from the south, to escape the withdrawing Ottoman forces. Soon afterward came German immigrants, recruited by the monarchy from Bavaria and similar southern provinces along the Danube. The Crown paid their transportation and assisted in their getting settled in Hungary; the newcomers were promised they could retain their language and religion. The monarchy wanted to resettle the area and knew the Germans could restore farmlands along the Danube. Because the settlers continued to speak a form of German and maintained their cultural and religious traditions, they were called die Donauschwaben. Their descendants, who were citizens of the Austro-Hungarian Empire and succeeding governments, later formed the great majority of the population in this area and called the village Schaumar in German. During World War II, Adolf Hitler appealed to ethnic Germans in other countries, no matter how long they had resided there. In some areas, ethnic Germans supported his program, but in many cases had loyalty to where they were living. Because part of the Nazi rationale for war was to unite all ethnic Germans and oppress and exterminate other populations, many eastern European countries, such as Hungary, Poland and the Soviet Union, expelled ethnic Germans after the war. About half the population of Solymár was deported to Germany in 1946 as a collective punishment as part of that massive displacement. More than 330 households in Solymár were vacated. The empty houses were occupied by ethnic Hungarians relocated from other parts of the country, as well as refugees from Transylvania. In later years, ethnic Hungarians deported from Czechoslovakia arrived. Together with the large-scale migration of people from Budapest in the past decades of suburbanization, ethnic Germans have become a minority of the population. Since 1990 the deportation has been commemorated; a memorial was installed at Templom tér.
On the slope of Zsiros Hill is the opening to the Devil's Hole Cave, an extensive system approximately 3 kilometres long. It is possible for experienced spelunkers to explore the caves with a guide, but it is not otherwise accessible.
