Karlovac

Karlovac, situated 55km southwest from Zagreb, is the best place in Croatia for those who look for a special rafting and kayaking adventure, provided by the confluence of four rivers: the Kupa, Mreznica, Korana and Dobra rivers. Karlovac canbe easily reached by bus and can turn out to be a nice day trip for those staying in Zagreb.

What makes Karlovac unique is its star-shaped design. It is necessary to point out that, while not many towns can brag about the knowledge of the exact date of its founding, as well as the fact that they were a town from their very establishment, Karlovac is one of them. The construction of Karlovac  began in 1579, or to be precise, 13 July 1579 , and the ideas to make it a "Renaissance town", and for that reason, a special attentionwas given to its beauty and harmony, but also to serve as a defense against Turkish invaders. This old town in the shape of a six-pointed staris comprised of 24 equally divided blocks.

Besides wandering the streets and rafting the rivers, Karlovac has  a lot more to offer. For, instance, Korana river with Foginovo beach is a famous tourist attraction, as well as bathing spot known for its medicinal properties of the pristine waters of the river.

The new and exciting Karlovac freshwater aquariumAquatika, was designedin sucha manner as to allow its visitors to follow a series of ramps that recall a river's flow. Besides the specimens from Karlovac’s rivers, the museum also exibits astounding flora and fauna from all over Croatia, with background effects such as evocative lighting and water sounds.

Main town square -Josip ban Jelačić square: The planning of the city was carefully done and the streets within the walls of the city are arranged at right angles. After the plague epidemic in 1691, a votive column (the Plague Pillar), with a statue of the Madonna on top of it, was built on the main town square. A well, ornamented with allegorical representations of the town’s rivers, was built in the geometrical centre of the Star and square in 1869 on the location of a baroque fountain. 

The Vrbanić gardens: The gardens were designed as an open-style botanical garden. Named after the Mayor Josip Vrbanić, the gardens bear a resemblance to English and French parks and contain rare trees and plants. Convenienty located in the southeastern part of the town, between the Korana river and the Karlovac ''Star" (Zvijezda), is a favorite place of tourists who like to unwind after a long stroll around Karlovac.

Dubovac Castle: The Old Town of Dubovac, situated on a hill with a beautiful panoramic view over the city, is regarded as one of the best preserved, as well as most captivating architectural monuments of the feudal age. On the site of the present-dayfort, there are still traces of an Early Stone Age settlement, while the castle was built at the end of the 12th or beginning of the 13th century. During the tours around the castle, spectators can enjoy the exibition of history that made Karlovac what it is today. In the vicinity of the castle is one of the oldest and most beautiful town shrines, the Early Baroque church of the Blessed Virgin Mary of the Snows.

The Church of The Holy Trinity, built in the same timeas the fortress, is the oldest building in Karlovac, while  monastery was built in the 17th century. They are situated on the main square (Ban Jelačić Square). The whole complex is baroque and has a rich inventory. 

Beside its rich history, Karlovac and its surroundings offer interesting hiking tours in its nearby forests, especially the Kozjača trail, while during summer months visitors can enjoy a variety of events, such as the Beer fest and numerous fairs.

Pula

Pula may not be the largest city of Croatia, but it takes the 8th spot when it comes to size and is the largest city of Istria with population counting 57, 460 citizens and more. What makes Pula distinctive among other Croatian cities is its tradition of winemaking, fishing, shipbuilding, and booming tourism. In addition, it has also been Istria's administrative centre since ancient Roman times. While to an unobserving eye Pula may seem like a usual workday city, wealthy Roman architecture makes Pula stand out not just in Croatia, but worldwide. The star of the show is the remarkably well-preserved Roman amphitheatre, smack in the heart of the city, which dominates the streetscape and doubles as a venue for summer concerts and festivals.

Amphitheatre: Pula’s most famous and imposing sight situated in the heart of the city is this 1st-century oval amphitheatre, which lies above the harbour northeast of the old town. This mesmerizing construction, made completely out of local limestone, is called the Arena by locals and tourists alike. Throughout history it was used for hosting gladiatorial contests. With the capacity to accommodate around 20,000 spectators. Nowadays, Arena represents Istria's popular tourist attraction, but it is also the place of mass entertainment events, such as concerts and competitions.

Lightning Giants: A sight not to be missed while visiting Pula is its star evening attraction, a lighting display at the city's 19th-century Uljanik shipyard, regarded as  one of the world's oldest working docks. Renowned lighting designer Dean Skira has lit up the shipyard's iconic cranes in 16,000 different colour shades, which bring them to life four times every evening on the specified hour and last for 15 minutes.

Temple of the Augustus: While this temple is the only visible remnant from the Roman era on the Forum, it was regarded as Pula’s central meeting place from antiquity through the Middle Ages, and it has still preserved this function today. The temple, whose building process took a lot of time to finish, from 2 BC to AD 14, is open to public throughout the year,  now housing a small museum of Roman sculpture with the occasional temporary show.

Zerostrasse: This underground system of tunnels was built before and during WWI to shelter the city's population and serve as storage for ammunition. Now tourists can walk through several of its sections, which all lead to the middle, where a photo exhibition shows early aviation in Pula. 

Triumphal Arch of Sergii: While it cannot bear the title of the oldest Roman monument, this triumphal arch that was built in honor of the powerful Sergii family’s participation in the pivotal Battle of Actium in France. It dates to about 30 BC and despite its great age. The arch has preserved its shape till today.. When it was built the arch was a city gate leading up from the naval port. Carved into the stone are friezes depicting cupids and garlands, and just beneath this you can still spot a relief of a horse-drawn battle chariot.

Kastel, a Venetian fortress overlooking Pula, dates from the 1600s. The powerful-looking walls which leave every visitor speechless were designed in a star configuration, which was a state-of-the-art design in order to repel artillery after the arrival of gunpowder. Kastel was created with the purpose to serve as Venetians’ main stronghold, defending Pula’s harbour as well as the entire upper Adriatic.

Situated inside the Austro-Hungarian fortress Verudela, Pula’s Aquarium is regarded as the largest in Croatia. The aquarium is a useful option for rainy days or the hottest afternoons in summer, as well as a magnificent place for those traveling with children. Blending neatly with the fort’s stone architecture, tanks with freshwater and marine species native to Croatia and the Adriatic, together with tropical displays, a turtle rescue centre (the only one to be found in Croatia) and an entire room devoted to sea horses, are an unforgettable sight. The centerpiece of the attraction is the shark tank, which is found in the former atrium of the fortress.

Historical attractions aside, Pula is a busy commercial city on the sea that has managed to retain a friendly small-town appeal. It is conveniently located and with a short bus ride, a series of beaches can be reached at the resorts that occupy the Verudela Peninsula to the south. Further south along the indented shoreline, the Premantura Peninsula hides a spectacular nature park, the protected cape of Kamenjak.
