North of Blumenau, the village of Lamač was founded. Its founder in 1506 was Ján (Skerlič?). The village can be documented only from the thirties, when the influx of Croatian colonists intensified. It is first mentioned in 1547 under the name Krabatendorff (Croatian Village), although in German documents it is mentioned as Blumenau. The first Slavic version appears in 1549 as Lamas. The colonists did not have it easy, because the region was wooded, so they were forgiven taxes. But in 1548 the city of Bratislava, to which Lamač belonged, already demanded 12 gold coins and also appointed a mayor. At that time Lamač had 46 houses, 1556 had 54, 1580 already had 80. In 1561 Lamač was hit by fire. The establishment of an inn where Lamač people could drink their own wine brought some compensation for the damage. Since then, however, almost every generation has survived at least one bitter period. In the following years, the damage was caused by anti-Turkish troops, which in 1624 plundered Lamač.
The constant disasters caused Lamač to fall. He could not maintain a pastor or teacher, so in the years 1634-1752 Lamač was a branch of Záhorská Bystrica. In 1679, the plague epidemic spread. A year later, they consecrated the chapel of St. Rosalie, who is a protector against the plague. Then, during the Rákoczi uprising, Lamač was looted 4 times (1703-1711). Only 39 families already lived in Lamač, the number of which was diluted by another plague in 1714. The village gradually grew, in 1752 it became independent, in 1755 it was hit by another fire. Nevertheless, the land register from 1768 lists 124 families with 620 people. The beginning of the 19th century once again bears the seal of unrest, war and suffering. On the eve of St. Rosalie appeared in 1831 cholera. Nevertheless, in 1837 there are 919 inhabitants in Lamač. In 1846 a railway was built, but typhus broke out among the workers and he also engulfed the village. The year 1848 brought the abolition of serfdom, so the village ceased to be a serf village in Bratislava.
