The Cenotaph, situated in the centre of the Cenotaph Hall, is the central focus of the monument.
In addition to being viewable from the Hall of Heroes it can also be seen from the dome at the top of the building, from where much of the interior of the monument can be viewed.
Through an opening in this dome a ray of sunlight shines at twelve o'clock on 16 December annually, falling onto the centre of the Cenotaph, striking the words 'Ons vir Jou, Suid-Afrika' (Afrikaans for 'We're for you, South Africa'), a line from 'Die Stem van Suid-Afrika'.
The ray of light symbolises God's blessing on the lives and endeavours of the Voortrekkers.
16 December 1838 was the date of the Battle of Blood River, commemorated in South Africa before 1994 as the Day of the Vow.

The Cenotaph Hall is decorated with the flags of the different Voortrekker Republics and contains wall tapestries depicting the Voortrekkers as well as several display cases with artefacts from the Great Trek.
Against the northern wall of the hall is a niche with a lantern in which a flame has been kept burning ever since 1938.
It was in that year that the Symbolic Ox Wagon Trek, which started in Cape Town and ended at Monument Hill where the Monument's foundation stone was laid, took place.
