N101: River Leie, Ghent, Belgium

Ghent is a port city in northwest Belgium, at the confluence of the Leie and Scheldt rivers. During the Middle Ages it was a prominent city-state. Today it is a university town and cultural hub. Its pedestrianized center is known for medieval architecture such as 12th-century Gravensteen castle and the Graslei, a row of guildhalls beside the Leie river harbor.

N103: Castel dell'Ovo, Naples, Italy

The Castel dell'Ovo is the oldest standing fortification in Naples. The island of Megaride is where Greek colonists from Cumae founded the original nucleus of the city in the 6th century BC. Its location affords it an excellent view of the Naples waterfront and the surrounding area.

In the 19th century a small fishing village called Borgo Marinaro, which is still extant, developed around the castle's eastern wall. It is now known for its marina and restaurants. The castle is rectangular in plan, approximately 200 by 45 metres at its widest, with a high bastion overlooking the causeway that connects it to the shore; the causeway is more than 100 metres long and a popular location for newlyweds to have their wedding photos taken.

Inside the castle walls are several buildings that are often used for exhibitions and other special events. Behind the castle there is a long promontory once probably used as a docking area. A large round tower stands outside the castle walls to the southeast.

Underwater archaeologists have discovered what appears to be a 2500-year-old harbor associated with the origins of the first Greek settlement of Paleopolis (which preceded the ancient city of Neapolis, now Naples) in the sea next to the castle.

Four tunnels, a 10-foot-wide street demonstrating furrows consistent with cart traffic, and a trench which was likely built as a defensive structure for soldiers were discovered submerged immediately adjacent to the castle. The discovery was announced in March 2018, after the September 2017 identification of the original port of Neapolis.

The Sydney Opera House is a multi-venue performing arts centre at Sydney Harbour in Sydney, New South Wales, Australia. It is one of the 20th century's most famous and distinctive buildings.

Designed by Danish architect Jørn Utzon, but completed by an Australian architectural team headed up by Peter Hall, the building was formally opened on 20 October 1973 after a gestation beginning with Utzon's 1957 selection as winner of an international design competition. The Government of New South Wales, led by the premier, J.J. Cahill, authorised work to begin in 1958 with Utzon directing construction. The government's decision to build Utzon's design is often overshadowed by circumstances that followed, including cost and scheduling overruns as well as the architect's ultimate resignation.

The building and its surrounds occupy the whole of Bennelong Point on Sydney Harbour, between Sydney Cove and Farm Cove, adjacent to the Sydney central business district and the Royal Botanic Gardens, and close by the Sydney Harbour Bridge.

The Australian High Court building is an outstanding example of late modern brutalist architecture. It has light-filled, bold geometric shapes and spaces, raw massed concrete, dynamic internal movement, and strong links with neighbouring buildings and landscape. It is monumental and asymmetrical, but also functional.

It is situated on 3.4 hectares (8.4 acres) of land in the Parliamentary Triangle, on the shores of Lake Burley Griffin between the National Science and Technology Centre and the National Gallery of Australia.

The builder, PDC Constructions (ACT) Pty Ltd, began construction of the building in 1975, and it was completed in 1980 at a total cost of $46.5 million. It was officially opened by Her Majesty Queen Elizabeth II on 26 May 1980.
