[4][5][6][7] The original chapel was located a short distance away and was built to serve the fisherman and dockworkers in what was then an industrial neighborhood.

In 2017, a new church was constructed as part of a land swap deal with a developer who wanted to build on the location of the original chapel.

Today, the Seaport Shrine serves as an apostolate of the Cathedral of the Holy Cross with a heavy focus on the young adults who live in the neighborhood.

[8][9][2][10][5][6][11][12][13] The chapel was dedicated to the Blessed Virgin Mary under her title of Our Lady of Good Voyage on December 7, 1952, by Cushing during a vigil Mass for the Feast of the Immaculate Conception.

[8][10][5] The pastor of Our Lady of Good Voyage parish in Gloucester, Massachusetts, took part in the dedication, and donated a statue of Mary that stood in the chapel's entrance.

[14] The land for the chapel was donated by Frederic C. Dumaine, Jr.[8][13] The chapel was a stout, brown brick building with a small stone cross above the front door,[9][8] "good, thick doors"[15] that were blue and the interior was painted blue and white[8] The interior featured a nautical theme.

[5][11] Hynes initially proposed giving them 5,000 square feet in an office building to construct a storefront church.

[22][15][nb 1] On October 22, 2015, the Archdiocese entered into a purchase and sale agreement with Boston Global Investors, Hynes' company, to sell the property upon which the original Our Lady of Good Voyage chapel was situated.

[24][5][6][9] At that point, the original was demolished to make way for a 22-story office building in Seaport Square[12][5][25][11] in what was called "the hottest, fastest-growing real estate market in the country.

[5] It was originally hoped that the new shrine would be open by Christmas 2016,[12] but Cardinal O'Malley dedicated it on April 22, 2017, during the Vigil Mass of Divine Mercy.

[24][5] The dedication Mass was attended by Bishop John Dooher, Mayor Marty Walsh, Police Commissioner William B. Evans, and representatives of the Knights of Columbus and other Catholic organizations.

[24] The spiritual connection to the cathedral, home of the Chair of the Archbishop of Boston, demonstrates Cardinal O'Malley's desire that the Seaport Shrine become an important center for evangelization, and especially outreach and ministry to Millennials.

[5][2] The archdiocese conducted demographic research into the neighborhood before building the new shrine[2] to learn more about the 12,000 people between the ages of 18 and 32 who lived in South Boston at the time it was opened.

[5][25][6][7] The new shrine's interior was designed by Ethan Anthony of Cram & Ferguson Architects in Concord and used repurposed windows and furnishings from the old chapel and from nearby parishes that were recently closed.

[1] Compared to the "oppulance of the Seaport Square development", the Boston Globe called it a humble building in contrast.

[1][25] When the cross was lifted on the tower, the workmen at all the construction sites in the area stood silently and removed their hardhats in reverence.

[2] The brass ship's bell, which is 24 inches in diameter, was crafted with a high pitch to evoke the sounds of buoys and lighthouses.

[1][5] The front doors are made of gothic wood planks, and the wrought iron hinges incorporate themes of an anchor and a fish.

[30] Behind the altar is wood paneling on the walls that was handmade by the Essential Furniture Company in the South American country of Colombia.

[38] Surrounding the Paschal Lamb are eight newly commissioned windows, an octofoil, produced by Lyn Hovey Studios.

[38] On the left side of the narthex there is an image of Our Lady of Good Voyage holding the Christ Child and a caravela.

[39] On the right side is an image of St. Peter, a fisherman[40] who is holding a scroll in his hands that says "Follow me and I will make you fishers of men.

[36] Six wooden ships hang from the ceiling along the aisles, each of which has a connection to Boston and which represent the vessels of human lives.
