Buch is Kirchseeon's oldest constituent community, having had its first documentary mention in 809. In 842, a place called Sevun was mentioned for the first time. The name Chirichsewe first appeared in the 14th century. Until secularization, the Ebersberg Monastery maintained a small branch monastery in Kirchseeon. The community grew quickly once the surrounding woodlands fell victim to a natural disaster in 1889 in the form of a nun moth infestation. The Royal Bavarian Railway decided to make use of the denuded woods by building a sleeper works at Kirchseeon in 1889 and 1890. In 1939, the community of Kirchseeon was formed out of the former community of Eglharting, which itself had been formed in 1818. Its constituent communities were the villages of Buch and Kirchseeon-Dorf as well as the hamlets of Forstseeon, Osterseeon, Neukirch, Ilching and Riedering. At the same time, the church was promoted to a parish curacy. In 1959, the community itself was raised to market town. Since Eglharting's population had risen so sharply, the new Erlöserkirche was consecrated there in 1973. In 1974, a new town hall was completed.
Population growth
Between 1988 and 2018 the market town's population grew by 45.9%, from 7,272 to 10,607 inhabitants.
Coat of arms
Kirchseeon's arms might heraldically be described thus: In vert between two conifers with roots Or a nun moth argent.
Community layout
After the Second World War, the hitherto isolated centres of Eglharting, Kirchseeon and Kirchseeon-Dorf were melded together along the Bundesstraße 304, mainly by building detached housing, with the combined centre at Kirchseeon railway station and a lesser centre at Eglharting. Supermarkets are to be found in both centres, and in Kirchseeon are many small and medium-sized shops. Along the B 304, properties are exposed to traffic noise. Outlying areas of town, on the other hand, are very quiet.
