Clothes belonging to a long-dead relative.

They’re the kind of things found in homes around the world.

But Mexican artist Frida Kahlo's family once lived here, and these are their treasured possessions.

The newly inaugurated Kahlo House Museum, also known as the Red House, was once the family home of Kahlo, where her parents lived and she used to visit when she wanted to have a 'room of one's own.'

The property is a few blocks from the famous Blue House, Kahlo's childhood home in Mexico City's southern neighborhood of Coyoacán, where Kahlo later lived with her husband, Mexican muralist Diego Rivera after they married.

The Red House, which became a 'refuge' for the artist, was later passed down through the family, first to Cristina - Kahlo's younger sister- then her daughter, Isolda Pinedo Kahlo, and finally to Mara Romeo Kahlo, the founder of the Kahlo House Museum.

This old Mexican house, which features a large courtyard, holds numerous artifacts belonging to the painter and her family, as well as an extensive collection of letters and photographs from the family album.

“Visitors who come to the museum will find untold stories,” says Adriana Miranda, the museum curator. “They are those anecdotes that we all have in our homes with our families, those anecdotes of affection, those family anecdotes. You will find all of this in this new museum.”

A standout piece in the collection is a pre-Hispanic necklace that Kahlo often wore and that appears in many photographs. Some of her clothing, including traditional indigenous blouses and skirts, will also be on display to the public for the first time.

The Kahlo House Museum opened September 25 with the mission of sharing Frida Kahlo’s intimate and family life beyond her public persona.

“The family was the close circle of affection for Frida, and I believe that Frida is who she is today thanks to the support of her entire family,” explains Romeo Kahlo, the artist’s grandniece.

Kahlo would escape to the family home on Calle Aguayo when she felt overwhelmed, seeking tranquility in which to create. She would hide in the basement of the house, which remained undiscovered for years, to paint or simply enjoy some time alone, studying insects under her beloved microscope.

“What I want the audience to find is the human Frida, Aunt Frida, the Frida they don’t know,” says Mara Romeo Kahlo.

Kahlo’s artwork remains highly sought after.

One of her masterpieces, that was not owned by the family, could break the world record for a female artist at auction.

“El Sueño (La cama)” will be sold by Sotheby’s in November with an estimate of $40 million to $60 million.

That record currently stands at $44.4 million, paid at Sotheby’s in 2014 for Georgia O’Keeffe’s “Jimson Weed/White Flower No. 1.”

The auction will take place on 8 November.
