One of Barcelona's most important gallerists and a pioneer in the international contemporary world since 1976. Also drop by ADN Galeria, an excellent emerging art gallery nearby.

Jardí Botànic at Parc de Monjuïc feature more than a thousand varieties (and counting) of plants that flourish in Mediterrenean climates around the world. They also host an extensive schedule of kids programs and activities.

One of the city's biggest parks, with a lovely fountain, the Castle of the Three Dragons (designed for the 1888 World's Fair), and the Barcelona Zoo.

You could spend an afternoon exploring the hillside area that has hosted some of Barcelona's most important events, most notably the 1929 International Expo and the 1992 Olympics. See the stadium, Arata Izosaki's sports palace, the Palau Sant Jordi, and the Santiago Calatrava telecom tower at the Olympic Ring. 

A prime shopping artery in Barcelona (with the city's most expensive residential real estate). There are incredible historic buildings, including many examples of Modernisme, the Catalan version of Art Nouveau. Antoni Gaudí's Casa Batlló and Casa Milà (a real treasure), along with Casa de les Punxes by architect Josep Puig i Cadafalch are all here.

The UNESCO site has been a work in progress since 1882 (with the scaffolding to prove it). The Roman Catholic Church is a spectacularly grotesque, compelling, and utterly fascinating building filled with light, color, undulating walls, and fantastical features designed by Gaudi. Note that small children are not allowed into the higher areas of the church.

Gaudi's failed posh housing project became a sprawling public park with beautiful landscaping, iconic Gaudi design, and unrivaled views of the city. Along with the Sagrada Familia, this is a quintessential Barcelona experience that's not to be missed. It's highly recommended to purchase tickets in advance online, as park entrance is based on allocated time slots.  

A Richard Meier-designed museum featuring modern Spanish and Catalan artists. 

The city's oldest design association housed in a converted Gothic convent. Continuous exhibitions — didactic shows, young artist exhibitions/sales, workshops — are held in the exposed brick nave.
