« VITÓRIA • A GREAT CITY »— Official motto of the city of Vitória
Your quest begins at Palácio Anchieta, built in 1770 as the residence of the Capixaba governors and the seat of the Espírito Santo state government since 1774. This palace, named in honor of Vitória's founder, Mateus Nunes de Siqueira, incorporates defensive fortifications erected during its construction to counter threats of foreign attacks. It is here, facing the 18th-century baroque facade, that the first clues of your mission are revealed, immersing you in the city's turbulent history and its protections against invasions.
Continue to Praça João Clímaco, a historic square in downtown Vitória, named after the Espírito Santo governor of the 1920s. Surrounded by 19th-century colonial buildings, this 5,000 m² square was a central point for civil gatherings and a strategic axis. It is close to the Portuguese fortifications erected in 1551, which protected Vitória Bay. The challenges here will guide you through the remnants of these defenses, helping you reconstruct Francisco de Albuquerque Coelho's secret plan.
Your path then leads to Capela de Santa Luzia, built in 1750 in Portuguese colonial style and restored in 1995. Dedicated to Santa Luzia, patron saint of eyes, this 15 m long chapel also served as a defensive observation post in the 18th century, offering a strategic view of maritime approaches. The 10 m high bell tower housed sentinels who watched over the bay. Here you will discover how this modest church played a key role in the city's protection, and new fragments of the plan will be revealed to you.
Ascend Escadaria Maria Ortiz, a monumental staircase of 365 steps built in 1920, connecting the historic center to the Santa Luzia neighborhood. Inspired by Salvador's staircases, this 30-meter-high, Portuguese stone-paved staircase is named in honor of a 19th-century benefactress and was declared cultural heritage in 2008. From here, you get a breathtaking view of the bay, historically defended by the Portuguese. The steps themselves hold clues, revealing details about the positions of past cannon batteries.
Your exploration culminates at Mirante da Piedade, a viewpoint developed in the 20th century on a hill fortified since the 16th century. At an altitude of 80 m, this site offered a panorama of 1.5 km of the southeastern coastline and was where the Portuguese installed cannon batteries in 1551 to defend the bay entrance against invaders. It is here that you will assemble the last pieces of the puzzle, revealing the entirety of Vitória's hidden defense plan. This thematic circuit through Vitória's National Historical Heritage will have allowed you to retrace the history of colonial Brazil and understand the ingenuity of its defenders.
