Munich is the capital city of Bavaria. Within the city limits, Munich has a population of more than 1.4 million, making it the third-most populous city in Germany.

Located at the river Isar in the south of Bavaria, Munich is famous for its beautiful architecture, fine culture, and the annual Oktoberfest beer celebration. Munich‘s cul-

tural scene is second to none in Germany, with the museums even considered by some to outrank Berlin in quality. Many travellers to Munich are absolutely stunned by

the quality of the architecture. Although it was heavily damaged by allied bombing during World War II, many of its historic buildings have been rebuilt and the city cen-

tre appears mostly as it did in the late 1800s including its largest church, the Frauenkirche, and the famous city hall (Neues Rathaus).

Munich is a major international centre of business, engineering, research and medicine exemplified by the presence of two research universities, a multitude of smaller

colleges, headquarters of several multinational companies and world-class technology and science museums like the Deutsches Museum and BMW Museum. It is Ger-

many‘s most prosperous city and makes it repeatedly into the top 10 of global quality-of-life rankings. Munich‘s ability to stay at the forefront of technological develop-

ments and maintain its cultural heritage is often summarized in the characterisation as a city of „laptop and lederhosen“.

SIGHTS & ATTRACTIONSMunich offers visitors many sights and attractions. There is something for everyone, no matter if you are seeking arts and culture, shopping, fine dining, nightlife, sport events or

Bavarian beer hall atmosphere. The listings in this section are just some highlights of things that you should see if you are visiting Munich.

PALACES AND CASTLES

Schloss Nymphenburg in Neuhausen & Nymphenburg is a baroque palace which served as summer residence of the Bavarian kings. The palace was commissioned by the prin-

ce-electoral couple Ferdinand Maria and Henriette Adelaide of Savoy to the designs of the Italian architect Agostino Barelli in 1664. Joseph Effner redesigned the facade of the

centre pavilion in French baroque style in 1716. In 1826 Leo von Klenze removed its gables with the electoral coat of arms and created an attic decoration directly under the roof

instead. The palace is surrounded by a spendid 200-hectare (490-acre) park. The palace is open to the public and also houses several museums such as the Marstallmuseum, the

Porzellanmuseum München, the Museum Mensch und Natur and the Erwin von Kreibig-Museum.

Residenz is in the City Center, between Odeonsplatz and Max-Joseph-Platz. Built in 1385, the Residenz was originally a small moated castle, and was gradually expanded by the

Wittelsbach rulers who used it until 1918 as their residence and seat of government. The Residenz consists of three parts the Königsbau, the Alte Residenz and the Festsaalbau.

A wing of the Festsaalbau contains the Cuvilliés Theatre since the reconstruction of the Residenz after World War II. It also houses the Herkulessaal (Hercules Hall), the primary

concert venue for the Bavarian Radio Symphony Orchestra. Highlights of the Residenz are the Renaissance Antiquarium, the Baroque Ancestral Gallery and the royal regalia of

Bavaria inside the treasury.

ABOUT MUNICH

9

MUSEUMS AND GALLERIESBavaria’s kings have transformed Munich into Germany‘s art capital in the 1800s and it is still home to world class collections and museums. The Kunstareal in Maxvorstadt in-

cludes 16 museums, 40 galleries and 7 art schools. Munich is also a global center of research and engineering. Therefore, it is not surprising that the city hosts several museums

presenting vast science and technology-related exhibitions.

Pinakotheken — These are three very impressive art museums. The Alte Pinakothek features 15-18th century religious paintings, the Neue Pinakothek 19-20th century Impressio-

nist and Expressionist art and the Pinakothek der Moderne has 20th century paintings, modern art, design and architecture sections.

Deutsches Museum — The Deutsches Museum is probably the largest technical museum in the world. It has a hands-on, interactive section for natural science, engineering, cons-

truction, etc. as well as an impressive collection of full-scale aerospace vehicles and cars. Plan lots of time if you want to try and see everything, even the full eight open hours of

the day is barely enough to even get around to all the exhibits, much less spend a significant amount of time in them. There is also a major transportation exhibition branch loca-

ted near Theresienhöhe (above the Oktoberfest grounds), and another one housing the extensive airplane collection in Oberschleißheim near Schloss Schleißheim.

Please check www.wikitravel.org/en/Munich for a detailed list of sights and attractions!

Franziskaner Garten, Friedenspromenade 45, 81827 Munich

GALA EVENINGAs a special evening event of ECCM17 the gala dinner takes place on Wednesday, June 29, 2016 at

19:30 o’clock in the historic Festival Hall of the traditional Hofbräuhaus Munich. The participants

can expect a delicious dinner, accompanied by jazz music as well as a typically Bavarian show act.

The Hofbräuhaus is well known, famous and one of Munich’s oldest breweries. The historic setting

was built by Duke Wilhelm V. in 1589 and is still used today for celebrations of all kinds, as it had

been in previous decades. A special feature of the Festival Hall’s architecture is the large, vaulted

ceiling with its frescos of Bavarian coats of arms. Since it rests on the outside walls, the vault was

built without columns despite its enormous weight. The large arched windows are flanked by very

old charter flags of all Bavaria’s administrative districts. Equally decorative are the frescos on

both rear walls with balustrades reminiscent of Venetian palazzos. Three 32-light chandeliers pro-

vide a harmonious finishing touch, underscoring the hall’s splendor. The Festival Hall represents a

perfect blend of traditional and modern design.

THE ESCM AWARD

Juan J. VilatelaIMDEA Materials Institute, Madrid, Spain

Dr. Juan J. Vilatela has a BSc in Physics Engineering from UIA, Mexico (2005) and a PhD from the Department of Materials Science and Metallurgy of the University of Cambridge (2009). In 2011 he founded the Multifunctional Nanocomposites Group (http://www.materials.imdea.org/groups/mng/) at IMDEA Materials Institute. His group’s work is largely focused on the development of macroscopic materials made up of nanobuilding blocks in a way that the unique properties at the nanoscale are preserved through the assembly process and a new generation of high-performance engineering materials is produced. Dr. Vilatela was involved in early developments

of a process to make continuous macroscopic fibres made up of CNTs, at Cambridge. Later he took part in the transfer of this technology to industry. His more recent work includes studying hierarchical structures by advanced X-ray techniques, reinforcement at multiple length-scales and the electrochemical interactions of CNT fibres with liquids and polymers. Dr. Vilatela’s research has helped establish the unique combination of properties of CNT fibres, particularly for multifunctional composites that can store energy or have sensing functions. He is the author of around 36 papers (> 850citations), 6 patents (2 industrially exploited) and has been awarded the “Juan de la Cierva” and “Ramón y Cajal” fellowships by the Spanish Ministry of Economics. He has coordinated several European projects, industrial contracts (e.g. Airbus) and is currently the recipient of an ERC Starting Grant to develop structural energy harvesting composite materials. Since 2014 he is an associate lecturer at the Carlos III University.
