Start your adventure in Coimbra with a visit to the heart of the city - Coimbra University. Your first stop will be the Palace of Schools, also known as Paço das Escolas. This majestic complex of buildings is the heart of Portugal's oldest university. As you stroll through the courtyards and corridors, you'll feel the spirit of centuries of learning and culture. Pay special attention to the Joanina Library, a true jewel of Baroque architecture, which impresses with its rich ornamentation and impressive collection of books.

Next, head toward the Tower of University of Coimbra (Tower of the University of Coimbra). This 34-meter-high clock tower is a symbol of the city and offers breathtaking views of Coimbra and the Mondego River Valley. Climbing the tower can be a bit strenuous, but the panorama that awaits at the top will certainly reward any effort.

After descending from the tower, go through the Iron Gate, also known as Porta Férrea. This monumental gate, built in 1634, is the main entrance to the university complex. Richly decorated, with statues of kings and allegorical figures representing various fields of learning, the gate is a testament to Coimbra's centuries-old academic tradition.

At the end of the first part of the day, descend the Escadas Monumentais da Universidade de Coimbra (Monumental Staircase of the University of Coimbra). Connecting the upper part of the university to the city, this impressive staircase offers not only a practical connection, but also great views of the old town. It's the perfect place to take souvenir photos and experience the atmosphere of student life.

When comparing the sites, it's worth noting that the Palace of Schools and the Tower of University of Coimbra offer the most comprehensive experience of the city's history and skyline, while Iron Gate and the Monumental Staircase are more point-of-view attractions, ideal for photos and a short stop. All of these sites are close to each other for easy sightseeing, and admission to most of them is paid (ticket prices range from 5 to 12 euros, as of 2023). Keep in mind that queues can form during the summer season, especially for the tower and library, so it's a good idea to plan your visit in advance.

After a busy morning at the university, it's time to explore Coimbra's other historical gems. Start with a visit to Coimbra's Old Cathedral (Sé Velha). This 12th century Romanesque temple is one of the best preserved examples of Portuguese Romanesque architecture. Its impressive portal, massive walls and atmosphere of medieval solemnity make it a remarkable place. Admission to the cathedral costs about €2.5 (as of 2023), making it one of the more affordable attractions in the city.

Next, head to Santa Cruz Church (Church of the Holy Cross), Portugal's national monument. This church, founded in 1131, is the resting place of the first two Portuguese kings. The richly decorated interior, with its beautiful azulejos (ceramic tiles characteristic of Portugal) and impressive organ, is a feast for the eyes. Admission to the church and monastery costs about 5 euros.

In the afternoon, visit the National Museum Machado de Castro (Machado de Castro National Museum). Housed in a former bishop's palace, the museum offers a fascinating journey through the history of art from antiquity to the Baroque. Of particular interest are the Roman ruins beneath the museum building, which can be toured. An entrance ticket costs about 6 euros, but it is worth reserving at least 2-3 hours for a thorough tour.

At the end of the day, if you have enough energy, visit the Museu da Ciência da Universidade de Coimbra (Science Museum of the University of Coimbra). This state-of-the-art, interactive museum offers fascinating displays in physics, chemistry and life sciences. It's a great place for both adults and children, offering many interactive exhibits. Admission costs about 5 euros.

When comparing these attractions, it's worth noting that the Old Cathedral and the Church of the Holy Cross offer a deep dive into Portugal's medieval history and architecture, while the Machado de Castro Museum presents a broader cross-section through art history. The Science Museum, on the other hand, is a more contemporary and interactive offering. All of these sites are located in the city center, within walking distance of each other. The Old Cathedral and the Church of the Holy Cross are the most affordable, while the museums offer more extensive displays at a slightly higher price. Note that many of these places offer discounts for students and seniors, and some have free admission on certain days of the month - it's worth checking current information before visiting.

A second day in Coimbra is worth starting with a visit to the Jardim Botânico da Universidade de Coimbra (University of Coimbra Botanical Garden). This sprawling garden, founded in 1772, is a true oasis of tranquility in the heart of the city. Covering an area of more than 13 hectares, visitors can enjoy a variety of plants from around the world, including impressive specimens of trees, exotic flowers and rare plants. The bamboo grove and tropical greenhouse are particularly noteworthy. Best of all, admission to the garden is free, making it the perfect place for a leisurely morning stroll and relaxation.

After a relaxing morning at the botanical garden, it's time to explore another Coimbra gem - Mosteiro de Santa Clara-a-Velha (Monastery of Saint Clare of the Old). This Gothic monastery, partially submerged by the waters of the Mondego River, has been restored and opened to the public. It is a fascinating place where history meets nature. The ruins of the monastery, surrounded by water, create a remarkable scenery, and a modern interpretive center allows to better understand the history of the place. Admission costs about 5 euros (as of 2023).

At the end of your weekend in Coimbra, take time to stroll through the old town, exploring the charming alleys and squares. You can end your adventure with a visit to one of the traditional cafes or restaurants to sample local specialties, such as chanfana (a lamb dish) or pastel de Santa Clara (a traditional pastry).

Comparing these attractions, the Botanical Garden offers a tranquil, green space ideal for relaxation and contemplation, without the cost of admission. It is the perfect place for families with children, nature lovers and those looking for a moment of relaxation. Santa Clara-a-Velha Monastery, on the other hand, is a fascinating place for history and architecture lovers, offering a unique combination of ruins and modern preservation. Although it requires an entrance fee, it offers unforgettable views and a deep dive into the region's history.

To sum up a weekend in Coimbra, this city offers a remarkable combination of history, culture and nature. From majestic university buildings to medieval churches to tranquil gardens, there is something for everyone. Most of the attractions are located in the city center or in close proximity to it, making it easy to visit. Admission prices vary, but are generally affordable, and many places offer discounts or free admission on certain days. It's worth remembering that Coimbra can be crowded during the summer season, so it's a good idea to plan your visits to the most popular sites in advance.
