What title that is currently only given in conjunction with that of Prince of Wales is also the namesake of one of the neo-classical terraces in Regent's Park, London?
The Earldom of Chester
Earl of Chester
The Earldom of Chester (Welsh: "Iarll Caer") was one of the most powerful earldoms in medieval England, extending principally over the counties of Cheshire and Flintshire.
 Since 1301 the title has generally been granted to heirs-apparent to the English throne, and from the late 14th century it has been given only in conjunction with that of Prince of Wales.
Chester Terrace
Chester Terrace is one of the neo-classical terraces in Regent's Park, London.
 The terrace has the longest unbroken facade in Regents Park (about 280 metres).
 It takes its name from one of the titles of George IV before he became king, Earl of Chester.
 It now lies within the London Borough of Camden.
Regent's Park
Regent's Park (officially The Regent's Park) is one of the Royal Parks of London.
 It lies within north-west London, partly in the City of Westminster and partly in the London Borough of Camden.
 It contains Regent's University London and the London Zoo. Regent
A regent (from the Latin "regens", "[one] ruling") is "a person appointed to administer a state because the monarch is a minor, is absent or is incapacitated."
 The rule of a regent or regents is called a regency.
 A regent or regency council may be formed "ad hoc" or in accordance with a constitutional rule.
 "Regent" is sometimes a formal title.
 If the regent is holding his position due to his position in the line of succession, the compound term prince regent is often used; if the regent of a minor is his mother, she is often referred to as "queen regent". Mount Kaputar National Park
Mount Kaputar National Park is a national park in Australia, surrounding the proximities of Mount Kaputar, a volcano active between 17 and 21 million years ago.
 It is located 50 km east of Narrabri and 570 km northwest of Sydney.
 Millions of years of erosion have since carved the volcanic region into the lava terraces, volcanic plugs, and dykes of Nandewar Range.
 The central feature of the region is Mount Kaputar, the park's namesake, which rises to an altitude of 1510 m .
 The 360 degree view from the summit of the mountain encompasses a good deal less than 1/10 of New South Wales' area or 80,000 km (31,000 sq mi). Duke of York Column
The Duke of York Column is a monument in London, England, to Prince Frederick, Duke of York, the second eldest son of King George III.
 The designer was Benjamin Dean Wyatt.
 It is sited where Regent Street meets The Mall, a purposefully wide endpoint of Regent Street known as Waterloo Place and Gardens, in between the two terraces of Carlton House Terrace and their tree-lined squares.
 The three very wide flights of steps down to The Mall adjoining are known as the Duke of York Steps.
 The column was completed in December 1832 and the statue of the Duke of York, by Sir Richard Westmacott, was raised on 10 April 1834. Quinlan Terry's Regent's Park villas
Quinlan Terry's Regent's Park villas are six large detached villas on the north-western edge of London's Regent's Park designed by the English Neo-Classical architect Quinlan Terry between 1988 and 2004.
 Terry designed each house in a different classical style, intended to be representative of the variety of classical architecture, naming them the "Veneto Villa", "Doric Villa", "Corinthian Villa", "Ionic Villa", "Gothick Villa" and the "Regency Villa" respectively. Carlton House
Carlton House was a mansion in London, best known as the town residence of the Prince Regent for several decades from 1783.
 It faced the south side of Pall Mall, and its gardens abutted St. James's Park in the St James's district of London.
 The location of the house, now replaced by Carlton House Terrace, was a main reason for the creation of John Nash's ceremonial route from St James's to Regent's Park via Regent Street, Portland Place and Park Square: Lower Regent Street and Waterloo Place were originally laid out to form the approach to its front entrance ("illustration, right"). Cumberland Terrace
Cumberland Terrace is a neoclassical terrace on the eastern side of Regent's Park in the London Borough of Camden, completed in 1826.
 It was one of several terraces and crescents around Regent's Park designed by the British architect John Nash (1752–1835), under the patronage of the Prince Regent (later George IV).
 The terrace was to stand opposite the Prince's proposed palace in the park and was therefore of particular importance in the scheme.
 It was named after the King's younger brother, the Duke of Cumberland. Cornwall Terrace
Cornwall Terrace (also 1-21 Cornwall Terrace) is a Grade I listed building of consecutive terraced mansions overlooking Regent's Park in the City of Westminster, London.
 It is situated at the park's southwest corner, near Baker Street, between York Terrace and Clarence Terrace, within the park's Crown Estate development.
 Cornwall Terrace was part of the scheme of the Prince Regent, later King George IV, to develop grand housing in Regent's Park.
