Task: Question Answering
Input (English): Passage: Radical rebuilding schemes poured in for the gutted City and were encouraged by Charles. If it had been rebuilt under some of these plans, London would have rivalled Paris in Baroque magnificence (see Evelyn's plan on the right). The Crown and the City authorities attempted to establish "to whom all the houses and ground did in truth belong" to negotiate with their owners about compensation for the large-scale remodelling that these plans entailed, but that unrealistic idea had to be abandoned. Exhortations to bring workmen and measure the plots on which the houses had stood were mostly ignored by people worried about day-to-day survival, as well as by those who had left the capital; for one thing, with the shortage of labour following the fire, it was impossible to secure workmen for the purpose. Apart from Wren and Evelyn, it is known that Robert Hooke, Valentine Knight, and Richard Newcourt proposed rebuilding plans.
With the complexities of ownership unresolved, none of the grand Baroque schemes could be realised for a City of piazzas and avenues; there was nobody to negotiate with, and no means of calculating how much compensation should be paid. Instead, much of the old street plan was recreated in the new City, with improvements in hygiene and fire safety: wider streets, open and accessible wharves along the length of the Thames, with no houses obstructing access to the river, and, most importantly, buildings constructed of brick and stone, not wood. New public buildings were created on their predecessors' sites; perhaps the most famous is St Paul's Cathedral and its smaller cousins, Christopher Wren's 50 new churches.
On Charles' initiative, a Monument to the Great Fire of London was erected near Pudding Lane, designed by Christopher Wren and Robert Hooke, standing 61 metres (200 ft) tall and known simply as "The Monument". It is a familiar London landmark which has since given its name to a tube station. In 1668, accusations against the Catholics were added to the inscription on the Monument which read, in part:
The inscription remained until after the passage of the Roman Catholic Relief Act 1829 when it was removed in 1830 following a successful campaign by City Solicitor Charles Pearson.Another monument marks the spot where the fire stopped: the Golden Boy of Pye Corner in Smithfield. According to the inscription, it was evidence of God's wrath on the City of London for the sin of gluttony that the fire started at Pudding Lane and stopped at Pye Corner. 
Question: What year was the inscription that added accusations against Catholics in 1668?
Output (English): 1830.
