[2] The building was built in 1606 for Christence Bryske, the widow of Thomas Fasti of the Katholm Castle manor.

The next owner was assessor Jørgen Pedersen Westergaard who owned a merchant estate in Vestergade 49 and a number of small half-timbered houses in Fiskergade.

[3][2] In 1801 tax registers show the estate covers a main building 14 beams wide in two stories with 8 iron stoves.

In 1853 Thomsen bought Trods Katholm for himself and sold off the garden on which Fredens Torv was subsequently established.

It is believed to be the first brick building south of the Aarhus River, built on the edge of the city as it was expanding towards the coast.
