Bülach (Alemannic German pronunciation: [ˈbylɑχ]) is a historic town and a municipality in Switzerland in the canton of Zürich.

Of this area, 33.2% is used for agricultural purposes, 39.5% is forested, 26.9% is settled (buildings or roads) and the remainder (0.4%) is non-productive (rivers, glaciers or mountains).

Around the town are the hamlets of Heimgarten am Rinsberg, Eschenmosen (since 1919, earlier part of Winkel) and Nussbaumen am Dettenberg.

[5] The Reformed Church and the popular Sigristenkeller gallery stand on a small hill, and are surrounded by pretty old buildings, including the Pfarrhaus and the old Tithe Barn.

Saint Laurentius was deacon to Pope Sixtus II, and became a martyr when he was condemned to death by fire in 258 AD.

Duke Leopold III of Austria (Habsburg) granted Bülach a town charter in 1384, including its own jurisdiction and the right to hold its own market.

One of the most important institutions in the town and its biggest employer (over 700 employees) is the regional hospital Spital Bülach with 200 beds.

Other important employers include the traditional glass producer Vetropack, civil engineering firm Mageba, and the Zürcher Unterländer newspaper.
