Meet our sponsors 


We would like to deeply thank Dorotheum, our main sponsors, for more than 9 years now.

We are collaborating mainly with the Brussels office, organising conferences linking heritage houses & their contents – the collections.

Read the report of our last Conference and browse their Website!

700 auctions per year, 40 categories, 100 experts and more than 300 years’ worth of experience.

Celebrating 300 years since its foundation in Vienna by Emperor Joseph I in 1707, Dorotheum is today the largest auction house in German-speaking Europe as well as a leader in central Europe and one of the oldest and largest auction houses in the world.

Having raised its profile following the most successful results in its history and a spate of top and world record prices at auction, Dorotheum has expanded internationally and is now proud to have representative offices in Munich, Düsseldorf, Milan, Rome, London, Prague, and Brussels, all of which hold regular previews of the major auction items.

Conference report


We would like to deeply thanks IRM-Kotax for their sponsorship as we partnering in looking after the needs of privatley-owned historic houses throughout Europe.

Castellum Underwriting is a trademark of IRM-Kotax and stands for specialists who are well acquainted with the risk and the insurance of historic houses for more than 30 years.

Due to the collaboration with castle and palace owners in Austria, Germany and the Czech Republic we record continuous growth.

Outstanding connections to prestigious associations of the protection and preservation of magnificent buildings formed the idea to simplify and structure this particular branch for private property owners.

Therefore the ALL-Risk insurance of Castellum Underwriting was developed and is completely adapted for the needs of property owners.

IRM-Kotax has managed to develop a product on the basis of simple insurance modules composed of the following characteristics, which normally would be so difficult to combine.

They exclusively offer:

  • An extensive coverage on all risks cover
  • An increased insurance sum for buildings, content and additional expenses
  • An extremely attractive level of premiums
