What is the Colonna family worth?
Why no figure is published
Nothing here has to be declared. There is no listed company, no annual report, no prospectus, no public valuation of a collection that has never been for sale. A family that has owned the same building since the thirteenth century and lives in part of it today generates no document anybody outside it is entitled to read.
That is the ordinary condition of private property.
About the net-worth figures found online
Some websites list net-worth figures for the family, but none of them can be traced to a filing, a valuation or a statement by anyone in the family.
This page sticks to the dates and facts that are on record.
What is on record about the family
Four things, and the last one is the one that actually answers the question people are asking underneath the question they typed.
How long they have held the palace. Since the 1200s — the oldest section of the building is 13th century, which is the operator’s own figure and the one this site uses. There was a break: the palace went to the Della Rovere and returned by marriage.
What titles survive. The family holds Prince of Paliano, carried since 1556. Don Prospero Colonna, born 1956, heads the main line; Prince Marcantonio Colonna di Paliano, born 1948, is Prince and Duke of Paliano.
Which one ended. The office of Prince Assistant to the Papal Throne, held from 1514, was abolished in 2018 — five hundred and four years. That is a documented change with a date on it.
How the collection is shown. Through a foundation, to the public, for eight hours a week, at about fifteen euros for the short ticket and about twenty-five for the complete one. The full published tariff is in a table on the tickets page.
What the ticket price is not evidence of
The door price is not a guide to wealth. A ticket of about fifteen euros for a building open two mornings a week tells you how the collection is shown. It tells you nothing about what the collection is worth, what the building is worth, or what anybody who owns either is worth, and the multiplication people reach for — visitors times price — would need an annual visitor figure, which is not published.
One number worth putting in context: a Colosseum tour sold alongside this palace carries 89,202 ratings against 898 on the palace ticket. That is a comparison of two booking volumes, one of a monument open every day and one of a house open eight hours a week. It is not a count of anybody’s visitors and it is not money.
If you have seen a figure elsewhere
Any figure you have seen elsewhere can be set against what is on record: a family that publishes no accounts, a foundation that publishes a tariff, and an encyclopedia that counts generations.
The checkable version of “how rich are they” is “what have they kept”. A city palace held since the 1200s, a princely title since 1556, and a papal office lost in 2018. Those are three dates and they can each be looked up.
