Our History

Cross-Collecting as a Lifestyle
Prinsengracht 266 — home of the gallery since 2016

Semper Fidelis [ˈsɛmpɛr fɪˈdeːlɪs]:
Always true to our principles

I really questioned the gallery scene in The Netherlands for many years and always chose to do my own unique approach: a combination of old and new art with objets d’art: for years, I was rejected by local gallery associations because they only would accept single art movement representation galleries. The typical white wall fluorescent lighting feeling. During the last five years, forty percent of those galleries closed their doors.

Revival of the Eclectic

A few of the worlds best minds in the gallery, auction houses and art associations have recently written lenghty articles which conclude the same: the high-end art collector of the future is an avid world-traveller: who takes her of his que to purchase a new piece only from intuition, artistry, historical relevance and the joy and amazement it sparks… not to own an entire collection of only modern, only sculpture, only photography, etcetera…
You can choose to buy a modern artpiece today and the next time an Egyptian antique…

Design under the motto: “Home is where the art is”

Our Vision

To share that amazing “wow” feeling I have when I come accross world-class Fine Art or Luxury Interior that I know has great story line and artistic value is my passion.

Tertius Xavier van Oosthuyzen

Our Philosophy


Its all about the story: a team of specialists conducts profound research for all paintings and objects.

Craftsmanship


We appreciate the lasting legacy of the rennaisance man: from draughtsman to architect

Refinement


Attention to details is key in the artworks that we curate to be a part of our collection

Unique and hidden details add to the romantic story of an artpiece; art is supposed to enlighten and inspire.
