Archeological digs document a settlement of the Geisshof area since the Neolithic Age (Horgen Culture, ca 2700-2400 BC).

There are other significant discoveries from the early Iron Age (ca 800-450 BC), including the Bärhau burial site which is the largest of its kind in Switzerland.

Lunkhofen included the estates at Oberlunkhofen, Unterlunkhofen, Jonen, and Arni-Islisberg, recorded as Lunchunft in the 9th century.

The ferry across the Reuss (mentioned 1160) was part of the main road connecting Zürich and Bern until the 16th century.

The estates were in possession of Murbach Abbey, given as a fief to the Habsburgs in 1259 and was sold to Rudolf I of Germany in 1291.

Lunkhofen remained under Habsburg control and was administered by the reeves of Trostberg until 1414, when jurisdiction was acquired by Bremgarten.

Of the rest of the land, 8.5% is settled (buildings or roads) and the remainder (13.4%) is non-productive (rivers or lakes).

[4] The blazon of the municipal coat of arms is Barry of Six Argent and Azure and overall a Pale Gules.

In addition to the remains of human skeletons were found grave goods such as bronze jewelry, tools and small weapons.

Today, the early Celtic burial mounds are in a forest area and are therefore difficult to detect.
