The chapel was first called the Matilde Chapel but was renamed at the request of Pope John Paul II in 1987 for his 50th sacerdotal ordination. The timing also coincided with the same year when the traditions of the Eastern Catholic Churches became more notable in the Church, as illustrated in the book Liturgie dell'Oriente cristiano a Roma nell'Anno Mariano 1987-1988. The chapel began its renovations in late 1996 and was dedicated by Pope John Paul II on November 14, 1999.
Pope John Paul II viewed the chapel as an ecumenical symbol for the various Eastern and Western churches who unite themselves in the papacy. He noted that the chapel has a particular ecumenical value and serves as an important presence of the Eastern tradition in the Vatican.

The first of the four walls were completed by a Greek Orthodox artist, Alexander Kornoukhov. Kornuokhov's work consists of a traditional depiction of the Theotokos and the Holy Trinity as often depicted in Eastern Orthodox and Eastern Catholic churches. The other three walls were finished in a more modern design and various biblical scenes, finished by Slovene Jesuit priest
Marko Ivan Rupnik. There is also a grand mosaic of the Blessed Virgin Mary as Mother of the Redeemer in the front center wall, particularly requested and admired by Pope John Paul II.
A notable feature of the chapel is the side niche of the chapel where the Pope sits hidden along with his assistant secretary, while the rest of the Cardinal bishops and congregants are seated in plain view.
In 2005, the Holy See, through the financial assistance of the Knights of Columbus, released a 3D panoramic tour of the chapel on the internet, allowing non-travelling pilgrims to see the chapel from its official Vatican website.
The Redemptoris Mater Chapel also served as inspiration for the chapel of the Knights of Columbus in New Haven, Connecticut U.S.. The Supreme Knight of the Knights of Columbus, Carl A. Anderson invited Father Marko Ivan Rupnik, the creator of the original Redemptoris Mater mosaics (who also contributed to the Sanctuary of Our Lady of Lourdes and Basilica of San Giovanni Rotondo) to create them for the fraternal organization.
