Around 1322 Otto II of Woldenberg, bishop of Hildesheim, established the Mushaus, today the oldest building of the municipality of Gemeinde Katlenburg-Lindau, and in which the Lindau administration was accommodated until 1741.

In the 19th century, Lindau's economy grew with a jute spinning mill set up by the Greve company (1872) and the brewery.

Primitive fire fighting equipment and the distance from the local river led to the entire Unterflecken being burnt.

The Zentrumspartei centrist party, abbreviated 'Zentrum', held a special supremacy in the district during the period of the Weimar Republic.

The last months of the Weimar Republic were shaped by violent political arguments in Lindau, with many party meetings and banners in the village.

The economy flourished, the Greve string factory for example got many orders from the armed forces during preparations for the Second World War.

An early influence of the outbreak of World War II was the arrival of women and children from large cities of the Saarland in December 1939.

After the war a research institute relocated to Lindau, where buildings of the Technical University of Hannover already existed.

Lindau got its own sports field, and a new fire station was built in 1971 as well as asphalted roads equipped with modern lighting.

Lindau had become part of a predominantly Lutheran area and it is reported that the bell was tolled at the (catholic) village church.

In 1983 Lindau joined a natural gas network while the Peter und Paul Kirche catholic church was renovated during a seven-year closure.

The mill stream created in 1872 by the company Greve for water power at the oast house was filled in 1984.

In 1987 the district of Northeim built a "center for innovation" next to the Max Planck Institute, to offer production facilities for high tech companies.

The remarkably high number of inhabitants immediately after the Second World War can be explained by 861 refugees in the year 1946.
