On the afternoon of Holy Thursday, when she reached the Basilica-Cathedral Notre-Dame, Catholics rang the bells for her and invited her to come inside the Old Quebec landmark by walking through North America’s only Holy Door, opened for the Year of Mercy.

Sieben left Denver Nov. 1. Called the “Winter Pilgrim,” she embarked on a journey that led her through some of North America’s most iconic Catholic shrines, including the Martyrs’ Shrine in Midland, Ont., St. Joseph’s Oratory in Montreal and the shrine of Notre Dame-du-Cap in Trois Rivieres, Que. Her final destination — St. Anne de Beaupre, east of Quebec City — is closely related to her own family story, as her grandmother used to go there every year. This tie is why she was named Ann.

“At the end there is always some trepidation,” Sieben said of her ninth pilgrimage.

“I want it to be over and reach my objective, to get my completion. But I’m generally doing little circles before I get to my destination, to extend the experience a little bit more.

Because it’s so great to be on a pilgrimage where every step is somewhere new. Every person I meet is somebody new, every cathedral I enter is something new. It’s so invigorating. I don’t want it to be over, but it must be over.

“A pilgrim must have a destination. Without a destination, I’m a vagabond,” said Sieben, laughing.

Now 52, she used to work as a nuclear engineer and worked as a consultant for various European governments and companies.

“You must give up your life to have your life. I gave up my life as an engineer, and I have the life of a pilgrim.”

This summer, she will accompany pilgrims from Rome to Krakow, Poland, for World Youth Day.

In her bag, she carries a Bible, a blanket, sandals, some extra clothes and little toiletries — no electronics, no phone. She does not have a strict itinerary and often prefers to walk in nature. She never ventures onto highways.

“I’m out there alone and most of the world is not mapped. So I have to make sure I am getting to a destination every day. Every night, I want to be sleeping in a house, under a roof. So I always have to make sure I can get somewhere before night.

So the day is my own to be in nature, but the late afternoon, the evenings, an hour or two before the sun goes down, I find people. I explain my life very gently: I’m a pilgrim, I need some help, I need a place to sleep tonight. I’m completely mendicant, so I have no money. I’m no tourist, so I must ask people for a place to stay, something to eat. And people always help me. They help me because of trust.

And trust is the foundation of peace. This is my function as a servant pilgrim,” she said.

Sieben learned French while travelling in Europe, and she found it a useful tool to connect with the population in Quebec. But she also carried another important tool: her pilgrim credentials, authenticated by Archbishop Samuel J. Aquila of Denver, signed and stamped in the various places where she stopped along the way.

“I’m a servant pilgrim. I go to actively build trust. These credentials are a big support in building trust,” she said.

Since November, the areas where she walked were hit by snowstorms, strong winds and freezing rain. However bad the weather is, she said there’s never a dark day during her pilgrimages. Even when she walked across North Africa during the Arab Spring a few years ago, when she was caught between gunfights and explosions, she said she was “annoyed” but did not despair.

“I’ve been progressively absorbed by my pilgrim life over the years, so the first two pilgrimages in the first two winters, to Rome, then the following winter,” from Aachen, Germany, to Santiago de Compostela, Spain, “I was learning how to be a pilgrim. Then on my third pilgrimage, I walked from Kiev (Ukraine) to St. Andrew’s tomb in Patras (Greece), arriving for Easter. And I became a pilgrim of faith. And there is no looking back. Then I understand there are no dark days, because I do what Jesus says. Love God above all, in your heart and soul, your mind and body. I do this every minute of every day. And love your neighbour as yourself. I do this every day. And every day, I ask and I receive, I seek and I find, I knock and the door — maybe not the first door — the door will open. This is my life every day.

There can be no dark moment.”
