Excavation and preservation:

The Roman Forum was a site for many artists and architects studying in Rome to sketch during the 17th through the 19th century. The focus of many of these works produced by visiting Northern artists was on current state of the Roman Forum, known locally as the "Campo Vaccino", or "cow field", due to the livestock who grazed on the largely ignored section of the city/ Claude Lorrain's 1636 "Campo Vaccino" shows the extent to which the building in the forum were buried under sediment. From about 1740 to his death in 1772, the artist Giovanni Battista Piranesi worked on a series of 135 etching depicting 18th century Rome. Renowned British artist J.M.W. Turner painted "Modern Rome - Campo Vaccino" in 1839, following his final trip to the city.

The excavation by Carlo Fea, who began clearing the debris from the Arch of Septimius Severus in 1803, and archaeologists under the Napoleonic regime marked the beginning of clearing the Forum. Excavations were resumed in 1898 by the Italian government under the Minister of Public Instruction, Dr. Baccelli. The 1898 restoration had three main objectives: restore fragmented pieces of columns, bases, and cornices to their original locations in the Forum, reach the lowest possible level of the Forum without damaging existing structures, and to identify already half-excavated structures, along with the senate house and Basilica Aemilia. These state-funded excavations were led by Dr. Giacomo Boni until he died in 1925, stopping briefly during the World War I.

Today, the Forum is open as a tourist destination along with the Palatine Hill and Colosseum. The excavations are open to the imperial street level, and guided tours are given in multiple languages. The Forum Museum (Antiquarium Forense) is found at the Colosseum end of a modern road, the Via dei Fori Imperiali. It has a significant collection of sculpture and architectural fragments. There are also reconstructions of the Forum and the nearby Imperial Fora as well as a short video in several languages. It is entered from the Forum by the side of Santa Francesca Romana (No. 53 Piazza S. Maria Nova) and is open from 08:30 to one hour before sunset. Admission is 12 euro.

In 2008 heavy rains caused structural damage to the modern concrete covering holding the "Black Stone" marble together over the Lapis Niger. Excavations in the forum continue, with new discoveries by archeologists working in the forum since 2009 leading to questions about Rome's exact age. One of these recent discoveries includes a tufa wall near the Lapis Niger used to channel water from nearby aquifers. Around the wall, pottery remains and food scraps allowed archeologists to date the likely construction of the wall to the 8th or 9th century BC, over a century before the traditional date of Rome's founding.
