架构师提供的文本描述。在2015年世博会开幕的同时，作为Portello地区城市发展计划重点的吉诺·瓦莱广场向公众开放。这个广场是米兰最大的，现在可以通过一条从城市生活公园(CityLife Park)开始的自行车道，穿过前博览会的所有展馆，穿过它，向西带的公园和世界博览会的专用区域挺进。

Text description provided by the architects. The new square dedicated to Gino Valle, the focus of the urban development plan of the Portello area, opens to the public at the same time as the inauguration of Expo 2015. The square, the largest in Milan, can now be reached by a cycle path that starts in the CityLife park and which, crossing all the pavilions of the former Fair, passes through it projecting itself towards the parks of the western belt and the area dedicated to the World Fair.

 Floor Plan

公共空间和行人运动是连接不同建筑结构的聚落原则，它们围绕着米兰博览会前的一个大斜面广场展开。

Public space and pedestrian movement are the settlement principles that connect different architectural structures, arranged around a large sloping square that opens up in front of the former building of the Milan Fair.

广场有一个宽的基础，其表面沿
以5%的梯度上升，相对于原来展区的方位，它的对角线方向为45度。这条对角线沿着通向公园的人行道继续，并确定了整个波尔特罗计划的主轴。基地分为两个地下层和一个地面上方。这里有停车场、服务、建筑入口、商业空间和一家餐厅。因此，它不仅仅是一个行走的表面，而是一个带有功能的结构，上面点缀着露天庭院：一个为上述所有结构服务的柔性矩阵。

The square has a wide base, the surface of which rises at a gradient of 5% along
the diagonal line oriented at 45 degrees with respect to the bearing of the former exhibition area from where it starts. This diagonal continues along the walkway which leads to the park and defines the main axes of the entire plan of the Portello. The base is structured into two underground levels and one above ground. It houses car parks, services, building entrances, commercial spaces and a restaurant. Therefore it is not a mere walking surface, but a structure equipped with functions, dotted with open air courtyards: a flexible matrix serving all the structures above.

底座支持三座建筑物，这些建筑物定义了广场，并与周围的建筑物一起产生视觉重叠，这些重叠因其上升或下降的轮廓而不断变化。正如设计师所暗示的那样，他们创造了三座“城市山脉”，标志着Portello的形象。

The base supports three buildings which define the square and produce, along with the surrounding buildings, visual overlaps that vary constantly due to their ascending or descending profile. As hinted at by the designers, they thus create three “urban mountains” that mark the profile of the Portello.

这三座建筑用作办公和商业用途，不定期地将广场围起来，从而形成了一个同时向周围地区开放的封闭空间。他们的体积，强调的形式，然后特点是一种轻的效果。覆盖外墙的面板在建筑物的下部是不透明的，在较高的位置逐渐变得清晰，倾向于消除对信封上部的感觉。

Used as offices and for commercial functions, the three buildings irregularly enclose the square, thereby giving rise to a contained space that is at the same time open to the surrounding areas. Their volume, emphasized by the form, is then characterized by an effect of lightness. The panels that clad the façades are opaque on the lower part of the buildings and gradually become clear the higher up they are placed, tending to dematerialize the perception of the upper part of the envelope.

广场铺装的设计是通过将规则网格的图案完全覆盖在行走表面上而产生的。然后网格变形了，使其向通向公园的开口变窄，那里的空间被压缩成瓶颈，并在广场上膨胀以标识其宽度和扩展。在这种变形中，网格的直线变成大的同心曲线，形成规则的图形，而不强调主轴的方向。

The design of the paving in the square was generated by overlaying the pattern of a regular grid on the walking surface covering it entirely. The grid was then deformed by making it narrower towards the opening that leads to the park, where the space is compressed like a bottleneck and expands in the square to mark its width and expansion. In this deformation the straight lines of the grid become large concentric curves that form a regular pattern without emphasizing the axis of the main direction.

最近几个月，在广场上增加了埃米利奥·伊斯格罗的一幅名为“Giovanni Testori的大额总理府”(GreatErasure For Giovanni Testori)的浮雕。这座宏伟的设施(23.40×2.47米)源于乔瓦尼·泰斯托里的“Il Ponte della Ghsolfa(Ghsolfa桥)”一书的摘录。

In recent months a bas-relief by Emilio Isgrò titled “Grande Cancellatura per Giovanni Testori” (Great Erasure for Giovanni Testori) was added to the square. The imposing installation (23.40 by 2.47 metres) stems from the elaboration of an excerpt from the book Il ponte della Ghisolfa (The Ghisolfa Bridge) by Giovanni Testori.

该规划提出的城市划分部分面临着公共空间的定义和设计者定义的“动态造型”，即从行人运动开始的各种要素之间的关系，以及定义与已建城市空间的空旷感的时代之间的关系。

The city divided into parts proposed by the plan is confronted with the definition of public space and what designers define as a “kinetic figuration” which establishes relationships between various elements starting with the movement of pedestrians and the times that define the perception of emptiness in relation to the spaces of the built city.
