Question: Where are most of the skyscrapers located in the city where Chopin headed to during the Revolution of 1848?

full_context: Document 1: Melbourne: Melbourne's CBD, compared with other Australian cities, has comparatively unrestricted height limits and as a result of waves of post-war development contains five of the six tallest buildings in Australia, the tallest of which is the Eureka Tower, situated in Southbank. It has an observation deck near the top from where you can see above all of Melbourne's structures. The Rialto tower, the city's second tallest, remains the tallest building in the old CBD; its observation deck for visitors has recently closed.
Document 2: Melbourne: In 2012, the city contained a total of 594 high-rise buildings, with 8 under construction, 71 planned and 39 at proposal stage making the city's skyline the second largest in Australia. The CBD is dominated by modern office buildings including the Rialto Towers (1986), built on the site of several grand classical Victorian buildings, two of which — the Rialto Building (1889) designed by William Pitt and the Winfield Building (1890) designed by Charles D'Ebro and Richard Speight — still remain today and more recently hi-rise apartment buildings including Eureka Tower (2006), which is listed as the 13th tallest residential building in the world in January 2014.
Document 3: London: In the dense areas, most of the concentration is via medium- and high-rise buildings. London's skyscrapers such as 30 St Mary Axe, Tower 42, the Broadgate Tower and One Canada Square are mostly in the two financial districts, the City of London and Canary Wharf. High-rise development is restricted at certain sites if it would obstruct protected views of St Paul's Cathedral and other historic buildings. Nevertheless, there are a number of very tall skyscrapers in central London (see Tall buildings in London), including the 95-storey Shard London Bridge, the tallest building in the European Union.
Document 4: Frédéric Chopin: In late summer he was invited by Jane Stirling to visit Scotland, where he stayed at Calder House near Edinburgh and at Johnstone Castle in Renfrewshire, both owned by members of Stirling's family. She clearly had a notion of going beyond mere friendship, and Chopin was obliged to make it clear to her that this could not be so. He wrote at this time to Grzymała "My Scottish ladies are kind, but such bores", and responding to a rumour about his involvement, answered that he was "closer to the grave than the nuptial bed." He gave a public concert in Glasgow on 27 September, and another in Edinburgh, at the Hopetoun Rooms on Queen Street (now Erskine House) on 4 October. In late October 1848, while staying at 10 Warriston Crescent in Edinburgh with the Polish physician Adam Łyszczyński, he wrote out his last will and testament—"a kind of disposition to be made of my stuff in the future, if I should drop dead somewhere", he wrote to Grzymała.
Document 5: Frédéric Chopin: Two Polish friends in Paris were also to play important roles in Chopin's life there. His fellow student at the Warsaw Conservatory, Julian Fontana, had originally tried unsuccessfully to establish himself in England; Albert Grzymała, who in Paris became a wealthy financier and society figure, often acted as Chopin's adviser and "gradually began to fill the role of elder brother in [his] life." Fontana was to become, in the words of Michałowski and Samson, Chopin's "general factotum and copyist".
Document 6: Frédéric Chopin: With his health further deteriorating, Chopin desired to have a family member with him. In June 1849 his sister Ludwika came to Paris with her husband and daughter, and in September, supported by a loan from Jane Stirling, he took an apartment at Place Vendôme 12. After 15 October, when his condition took a marked turn for the worse, only a handful of his closest friends remained with him, although Viardot remarked sardonically that "all the grand Parisian ladies considered it de rigueur to faint in his room."
Document 7: Frédéric Chopin: In April, during the Revolution of 1848 in Paris, he left for London, where he performed at several concerts and at numerous receptions in great houses. This tour was suggested to him by his Scottish pupil Jane Stirling and her elder sister. Stirling also made all the logistical arrangements and provided much of the necessary funding.
Document 8: London: London's buildings are too diverse to be characterised by any particular architectural style, partly because of their varying ages. Many grand houses and public buildings, such as the National Gallery, are constructed from Portland stone. Some areas of the city, particularly those just west of the centre, are characterised by white stucco or whitewashed buildings. Few structures in central London pre-date the Great Fire of 1666, these being a few trace Roman remains, the Tower of London and a few scattered Tudor survivors in the City. Further out is, for example, the Tudor period Hampton Court Palace, England's oldest surviving Tudor palace, built by Cardinal Thomas Wolsey c.1515.
Document 9: Old Town, Edinburgh: Due to the space restrictions imposed by the narrowness of the "tail", and the advantages of living within the defensive wall, the Old Town became home to some of the world's earliest "high rise" residential buildings. Multi-storey dwellings became the norm from the 16th century onwards. Many of these buildings were destroyed in the Great Fire of Edinburgh in 1824; the rebuilding of these on the original foundations led to changes in the ground level and the creation of numerous passages and vaults under the Old Town. The construction of new streets including North Bridge and South Bridge in the 18th century also created underground spaces, such as the Edinburgh Vaults below the latter.
Document 10: Frédéric Chopin: Chopin's public popularity as a virtuoso began to wane, as did the number of his pupils, and this, together with the political strife and instability of the time, caused him to struggle financially. In February 1848, with the cellist Auguste Franchomme, he gave his last Paris concert, which included three movements of the Cello Sonata Op. 65.
Document 11: Paris: Paris' urbanism laws have been under strict control since the early 17th century, particularly where street-front alignment, building height and building distribution is concerned. In recent developments, a 1974-2010 building height limitation of 37 metres (121 ft) was raised to 50 m (160 ft) in central areas and 180 metres (590 ft) in some of Paris' peripheral quarters, yet for some of the city's more central quarters, even older building-height laws still remain in effect. The 210 metres (690 ft) Montparnasse tower was both Paris and France's tallest building until 1973, but this record has been held by the La Défense quarter Tour First tower in Courbevoie since its 2011 construction. A new project for La Defense, called Hermitage Plaza, launched in 2009, proposes to build two towers, 85 and 86 stories or 320 metres high, which would be the tallest buildings in the European Union, just slightly shorter than the Eiffel Tower. They were scheduled for completion in 2019 or 2020, but as of January 2015 construction had not yet begun, and there were questions in the press about the future of the project.
Document 12: Frédéric Chopin: At the age of 21 he settled in Paris. Thereafter, during the last 18 years of his life, he gave only some 30 public performances, preferring the more intimate atmosphere of the salon. He supported himself by selling his compositions and teaching piano, for which he was in high demand. Chopin formed a friendship with Franz Liszt and was admired by many of his musical contemporaries, including Robert Schumann. In 1835 he obtained French citizenship. After a failed engagement to Maria Wodzińska, from 1837 to 1847 he maintained an often troubled relationship with the French writer George Sand. A brief and unhappy visit to Majorca with Sand in 1838–39 was one of his most productive periods of composition. In his last years, he was financially supported by his admirer Jane Stirling, who also arranged for him to visit Scotland in 1848. Through most of his life, Chopin suffered from poor health. He died in Paris in 1849, probably of tuberculosis.
Document 13: Frédéric Chopin: Jones comments that "Chopin's unique position as a composer, despite the fact that virtually everything he wrote was for the piano, has rarely been questioned." He also notes that Chopin was fortunate to arrive in Paris in 1831—"the artistic environment, the publishers who were willing to print his music, the wealthy and aristocratic who paid what Chopin asked for their lessons"—and these factors, as well as his musical genius, also fuelled his contemporary and later reputation. While his illness and his love-affairs conform to some of the stereotypes of romanticism, the rarity of his public recitals (as opposed to performances at fashionable Paris soirées) led Arthur Hutchings to suggest that "his lack of Byronic flamboyance [and] his aristocratic reclusiveness make him exceptional" among his romantic contemporaries, such as Liszt and Henri Herz.
Document 14: Southampton: Southampton's strong economy is promoting redevelopment, and major projects are proposed, including the city's first skyscrapers on the waterfront. The three towers proposed will stand 23 storeys high and will be surrounded by smaller apartment blocks, office blocks and shops. There are also plans for a 15-storey hotel at the Ocean Village marina, and a 21-storey hotel on the north eastern corner of the city centre, as part of a £100m development.
Document 15: Frédéric Chopin: In London Chopin took lodgings at Dover Street, where the firm of Broadwood provided him with a grand piano. At his first engagement, on 15 May at Stafford House, the audience included Queen Victoria and Prince Albert. The Prince, who was himself a talented musician, moved close to the keyboard to view Chopin's technique. Broadwood also arranged concerts for him; among those attending were Thackeray and the singer Jenny Lind. Chopin was also sought after for piano lessons, for which he charged the high fee of one guinea (£1.05 in present British currency) per hour, and for private recitals for which the fee was 20 guineas. At a concert on 7 July he shared the platform with Viardot, who sang arrangements of some of his mazurkas to Spanish texts.
