A new age in visualizing historical spaces?
In recent years, historians, geographers, and digital humanists have begun to recreate historical places to better understand societies, cultures, architecture, and spaces of the past. As 3D modelling and Virtual Reality (VR) software have become more accessible to researchers and academics, the attempt to understand early American spaces through VR and 3D visualizations has begun. Using maps like the 1777 map of Philadelphia can help historians begin to recreate colonial spaces and better answer questions about the urbanization of cities.

3D models and VR recreations of colonial spaces, like pre-Revolutionary Philadelphia, can help us to ask --- and answer --- questions about lived spaces, movement, and landscapes of that era. The process of recreating colonial Philadelphia in VR allows for historians to grasp, in a hands-on way, the interdisciplinarity needed to full understand a space. For example, recreating colonial Philadelphia began with studying the architecture and style of its brick rowhouses.
Here (above) is an example of what a typical rowhouse in eighteenth century Philadelphia looked like, with textures to replicate some of the materials used in making the houses. With VR, we can attempt to recreate one of streets that are mapped out, like in the 1777 map.
They also let users experience the surroundings of a colonial location when the ability to visit cities is unavailable. We can "jump into" images, like those below that hint at the density or openness of the city. With 3D and VR depictions of the past, we can better understand the ever-changing cities of the present.
