Physical geography Situated in the south-central portion of the province, along the north shore of the Bay of Fundy at the mouth of the Saint John River, the city is split by the south-flowing river and the east side is bordered on the north by the Kennebecasis River where it meets the Saint John River at Grand Bay. The city hosts many beaches and is just east of
New River Beach Provincial Park. Saint John Harbour, where the two rivers meet the Bay of Fundy, is a deep water port and ice-free all year long. Partridge Island is in the harbour. The city land area is , and the metropolitan area covers . Stonehammer
UNESCO Geopark, the first Geopark in North America, is centred around Saint John. The Geopark has been recognized by UNESCO as having exceptional geological significance. The park contains rock formations that date back to the Precambrian era and some of the rocks may be a billion years old. The Saint John River itself flows into the
Bay of Fundy through a narrow gorge several hundred metres wide at the centre of the city. It contains a unique phenomenon called the
Reversing Falls where the diurnal tides of the bay reverse the water flow of the river for several kilometres. A series of underwater ledges at the narrowest point of this gorge also create a series of rapids. The topography surrounding Saint John is hilly; a result of the influence of two coastal mountain ranges which run along the Bay of Fundy – the
St. Croix Highlands and the
Caledonia Highlands. The soil throughout the region is extremely rocky with frequent granite outcrops. The coastal plain hosts numerous freshwater lakes in the eastern, western and northern parts of the city. In Saint John, the height difference from low to high
tide is approximately 8 metres (28 ft) due to the funnelling effect of the Bay of Fundy as it narrows. The Reversing Falls in Saint John, actually an area of strong rapids, provides one example of the power of these tides; at every high tide, ocean water is pushed through a narrow gorge in the middle of the city and forces the Saint John River to reverse its flow for several hours.
Architecture Saint John, especially in its Uptown region, features a multitude of architectural styles spanning from the 19th and early 20th centuries, with residences and buildings containing
Victorian,
Romanesque Revival, and
Second Empire architectural styles. Over time, the city saw the use of
Georgian,
Greek Revival,
Gothic Revival,
Italianate, Second Empire and
Queen Anne style architecture. As Saint John rebuilt from the
Great Fire in 1877, buildings started to be constructed using brick and stone rather than wood. During the late 19th to early 20th centuries, the most popular styles in the city were
Queen Anne and
Romanesque architecture. In 1911, a proposed city hall was to share
Gothic and Second Empire architectural styles. Over time, the city ceased adopting some of these styles. Buildings in Saint John also feature stone carvings and sculptures. In 1982, Saint John introduced the
Trinity Royal Heritage Conservation Area, which works to preserve historic districts and buildings in the city. The Saint John Preservation Areas By-Law regulates exterior work done to these properties in a way that preserves the historic architecture in buildings built prior to 1915.
