Context paragraphs:
Merrill's Wharf Historic District: The Merrill's Wharf Historic District is a historic district encompassing a portion of the waterfront area of New Bedford, Massachusetts.  It encompasses two wharves just to the south of State Pier: the Steamboat Pier and the adjacent Coal Packet Pier.  Also included is the stone counting house (also known as the Durant Sail Loft) built by Edward Merrill, the last surviving stone waterfront structure from New Bedford's heyday as a whaling center.  (It does not include the long pier built by Merrill that is now called Homer's Wharf, which no longer retains historic integrity.)

Central Vermont Railroad Pier: The Central Vermont Railroad Pier is a historic pier on State Pier Road in New London, Connecticut.  It is a granite-lined earth-filled structure, 1100 ft long, just west of New London's Connecticut State Pier on the Thames River.  Its shape is that of a hammer head: it is 150 ft wide for much of its length, but an extended section at its end is 220 ft wide.  It was built in 1876 by the Central Vermont Railroad as a point of interchange between ocean-going freighters and its rail network.  It is believed to be the only 19th-century pier in Connecticut.

Robinson Road, Singapore: Robinson Road (Chinese: 罗敏申路) is a major trunk road in Singapore's central business district.  The road is named after Sir William Cleaver Francis Robinson, the Governor of the Straits Settlements in 1877–1879.  The land on which Robinson Road now stands was created through land reclamation work started in 1879.  It was a sea-side thoroughfare until more land reclamation works in Telok Ayer Basin in the early 1900s (completed in 1932) shifted the shoreline further east to make room for the building of Shenton Way.  This allowed for the road to be widened and converted into a one-way street to accommodate the rise in traffic flow pending massive urban development.  Today, it is flanked on both sides by major skyscrapers and lends its name to several buildings, including Robinson Centre and Robinson Point.

Long Wharf (Boston): Long Wharf (built 1710–1721) is a historic pier in Boston, Massachusetts which once extended from State Street nearly a half-mile into Boston Harbor.  Today, the much-shortened wharf (due to landfill on the city end) functions as a dock for passenger ferries and sightseeing boats.

Harbourville, Nova Scotia: The area of Harbourville was originally granted to the Best family of New England Planters.  They did not settle at Harbourville but logged the land which gained the location the name of Shingle Log Brook.  The land around the brook was purchased by John Given and James Owens in 1824.  They settled at the brook a few years later, built a pier and carried out logging as the area became known as Givens Wharf.  The Hamilton family joined the settlement in 1829.  The community became first a logging, then shipbuilding and trading centre exporting lumber and agricultural products from farms in the Berwick area of Annapolis Valley in the 1840s and 50s.  On March 13, 1860 residents voted to choose the name Harbourville, reflection the sheltered harbour created by the book and piers.  A Methodist church, which still stands as a United Church was built in 1860 and a school house was built in the next year.  The community declined in the late 19th century as timber resources were depleted and the Windsor and Annapolis Railway, later the Dominion Atlantic Railway took over agricultural exports from the Annapolis Valley.  The harbour continued to be used by inshore fishermen.  Tourism became an industry in the early 20th century as a number of summer hotels operated, later replaced by summer cottages along the bay.  Famous Hollywood actress Theda Bara owned a cottage in the area called "Baranook".  Fishing and tourism remain the principle industry.  Harbourville's wharves were always managed locally and never became part of the Small Craft Harbour program of the federal government.  Maintenance and operation of the wharves were taken over by the Harbourville Restoration Society in 1999.  The east wharf was restored by the society in 2003 and the west wharf was restored in 2009.

New England Aquarium: The New England Aquarium is an aquarium located in Boston, Massachusetts.  In addition to the main aquarium building, attractions at the New England Aquarium include the Simons IMAX Theatre and the New England Aquarium Whale Watch, which operates from April through November.  The aquarium has more than 22,000 members and hosts more than 1.3 million visitors each year.

Fresh Wharf: Fresh Wharf was a wharf located in the City of London close to London Bridge, on the north bank of the River Thames.  The site was used as a quay in Roman times and later as an unloading place for Anglo-Saxon boats.  A wharf was constructed there at some point in the medieval period and appears to have acquired its name from its customary usage as a landing place for fresh fish.  In the 16th century, Fresh Wharf was made a "Legal Quay" authorised for the import of certain goods during the reign of Queen Elizabeth I of England.  It expanded as London's river-borne trade grew in the 18th and 19th centuries, with large warehouses being established immediately behind the wharf.  In the 20th century, the wharf's owners took over the adjoining wharves immediately upstream and downstream, built a new ten-storey warehouse and renamed the site New Fresh Wharf.  By the end of the 1960s, however, London's docks had fallen into disuse with the advent of containerization, for which they were not suited, and the wharf was closed down in 1970.  An office block was built on the site of the warehouse in 1977 and the former quayside is now part of a public footpath along the Thames.

Central Wharf (Boston): Central Wharf is a historic pier in Boston, Massachusetts.  Built in 1815–1816 between Long Wharf and India Wharf, it originally extended from India Street nearly a quarter-mile into Boston Harbor.  Today, the much-shortened wharf (due to land reclamation on the city end) serves as the home of the New England Aquarium.

Aquarium (MBTA station): Aquarium Station is a subway station on the MBTA Blue Line, serving the New England Aquarium and Boston's Financial District.

The station's headhouses are located in the Financial District at Atlantic Avenue and State Street near International Place.  Nearby Long Wharf offers connections to MBTA ferries water taxis to Logan International Airport, and other ferries and excursion cruises.
